Takes a definition form whose shape is like @scheme[define] (though
|
|
possibly with a different name) and returns two values: the defined
|
|
identifier and the right-hand side expression.
|
|
|
|
To generate the right-hand side, this function may need to insert uses
|
|
of @scheme[lambda]. The @scheme[lambda-id-stx] argument provides a
|
|
suitable @scheme[lambda] identifier.
|
|
|
|
If the definition is ill-formed, a syntax error is raised. If
|
|
@scheme[check-context?] is true, then a syntax error is raised if
|
|
@scheme[(syntax-local-context)] indicates that the current context is
|
|
an expression context. The default value of @scheme[check-context?] is
|
|
@scheme[#t].
|
|
|
|
If @scheme[opt-kws?] is @scheme[#t], then arguments of the form
|
|
@scheme[[id expr]], @scheme[keyword id], and @scheme[keyword [id
|
|
expr]] are allowed, and they are preserved in the expansion.}
