[procedure] (get-line-number EXPR)
If EXPR is a pair with the car being a symbol, and line-number information is available for this expression, then this procedure returns the associated line number. If line-number information is not available, then #f is returned. Note that line-number information for expressions is only available in the compiler.
[procedure] (expand X)
If X is a macro-form, expand the macro (and repeat expansion until expression is a non-macro form). Returns the resulting expression.
[procedure] (syntax-error [LOCATION] MESSAGE ARGUMENT ...)
Signals an exception of the kind (exn syntax). Otherwise identical to error.
