* (which may be " or {) up to but not including
* the space, semicolon, or bracket that
* terminates the word. NumComponents counts the
* total number of sub-tokens that make up the
* word. This includes, for example, sub-tokens
* of TCL_TOKEN_VARIABLE tokens.
* TCL_TOKEN_SIMPLE_WORD - This token is just like TCL_TOKEN_WORD except
* that the word is guaranteed to consist of a
* single TCL_TOKEN_TEXT sub-token.
* TCL_TOKEN_TEXT - The token describes a range of literal text
* that is part of a word. NumComponents is
* always 0.
* TCL_TOKEN_BS - The token describes a backslash sequence that
* must be collapsed. NumComponents is always 0.
* TCL_TOKEN_COMMAND - The token describes a command whose result
* must be substituted into the word. The token
* includes the enclosing brackets. NumComponents
* is always 0.
* TCL_TOKEN_VARIABLE - The token describes a variable substitution,
* including the dollar sign, variable name, and
* array index (if there is one) up through the
* right parentheses. NumComponents tells how
* many additional tokens follow to represent the
* variable name. The first token will be a
* TCL_TOKEN_TEXT token that describes the
* variable name. If the variable is an array
* reference then there will be one or more
* additional tokens, of type TCL_TOKEN_TEXT,
* TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
* TCL_TOKEN_VARIABLE, that describe the array
* index; numComponents counts the total number
* of nested tokens that make up the variable
* reference, including sub-tokens of
* TCL_TOKEN_VARIABLE tokens.
* TCL_TOKEN_SUB_EXPR - The token describes one subexpression of an
* expression, from the first non-blank character
* of the subexpression up to but not including
* the space, brace, or bracket that terminates
* the subexpression. NumComponents counts the
* total number of following subtokens that make
* up the subexpression; this includes all
* subtokens for any nested TCL_TOKEN_SUB_EXPR
* tokens. For example, a numeric value used as a
* primitive operand is described by a
* TCL_TOKEN_SUB_EXPR token followed by a
* TCL_TOKEN_TEXT token. A binary subexpression
* is described by a TCL_TOKEN_SUB_EXPR token
* followed by the TCL_TOKEN_OPERATOR token for
* the operator, then TCL_TOKEN_SUB_EXPR tokens
* for the left then the right operands.
* TCL_TOKEN_OPERATOR - The token describes one expression operator.
* An operator might be the name of a math
* function such as "abs". A TCL_TOKEN_OPERATOR
* token is always preceeded by one
* TCL_TOKEN_SUB_EXPR token for the operator's
* subexpression, and is followed by zero or more
* TCL_TOKEN_SUB_EXPR tokens for the operator's
* operands. NumComponents is always 0.
* TCL_TOKEN_EXPAND_WORD - This token is just like TCL_TOKEN_WORD except
* that it marks a word that began with the
* literal character prefix "{*}". This word is
* marked to be expanded - that is, broken into
* words after substitution is complete.
