Parse.parse_in_context : term list -> term quotation -> term
STRUCTURE
SYNOPSIS
Parses a quotation into a term, using the terms as typing context.
LIBRARY
Parse
DESCRIPTION
Where the Term function parses a quotation in isolation of all possible contexts (except inasmuch as the global grammar provides a form of context), this function uses the additional parameter, a list of terms, to help in giving variables in the quotation types.

Thus, Term`x` will either guess the type ``:'a`` for this quotation, or refuse to parse it at all, depending on the value of the guessing_tyvars flag. The parse_in_context function, in contrast, will attempt to find a type for x from the list of free variables.

If the quotation already provides enough context in itself to determine a type for a variable, then the context is not consulted, and a conflicting type there for a given variable is ignored.

FAILURE
Fails if the quotation doesn’t make syntactic sense, or if the assignment of context types to otherwise unconstrained variables in the quotation causes overloading resolution to fail. The latter would happen if the variable x was given boolean type in the context, if + was overloaded to be over either :num or :int, and if the quotation was x + y.
EXAMPLE
   << There should be an example here >>

USES
Used in many of the Q module’s variants of the standard tactics in order to have a goal provide contextual information to the parsing of arguments to tactics.
