[Gauche-devel] redefining "define" does not result in an error

[<Dek...@Ya...>]

In Gauche 0.9, redefining "define" does not result in an error,
contradicting Section 5.3 of the "Revised^5 Report on the Algorithmic
Language Scheme" (see
http://www.schemers.org/Documents/Standards/R5RS/HTML/r5rs-Z-H-8.html);
_viz._:

        gosh> (define define 3)
        define
        gosh> define
        3
        gosh> (define first car)
        *** ERROR: invalid application: (3 #0=#<subr car> #0#)
        Stack Trace:
        _______________________________________
        gosh> 

Section 5.3 specifically states the following:

> ... it is an error for a definition or syntax definition to shadow a
> syntactic keyword whose meaning is needed to determine whether some form
> in the group of forms that contains the shadowing definition is in fact
> a definition.... For example, the following are errors:
> 
> (define define 3)

Perhaps this discrepancy should be resolved.
