Subject: r6rs incompatibilities
Date: Fri, 21 May 2010 11:54:42 +0200 [thread overview]
Message-ID: <m3ljbd1swt.fsf@pobox.com> (raw)
Hi,
While I'm thinking about it, I thought I'd mention a couple of
incompatibilities between Guile and R6RS:
* In r6rs, internal definitions expand to letrec*, not letrec. Guile
does not support letrec*, though that would be nice.
* The R6RS specifies many situations in which a conforming
implementation must signal a specific error. Guile doesn't really
care about that too much -- if a correct R6RS program would not hit
that error, we don't bother checking for it.
* Multiple `library' forms in one file are not yet supported. This is
because the expansion of `library' sets the current module, but does
not restore it. This is a bug I think.
* I'm sure there are other points -- please test and reply :)
Andy
