i do not want to implement things that are not portable to others schemes
using standart macros and SRFI,
for now my Scheme+ is a set of macros portable to other scheme and use only
SRFI if they are implemente

i read your code, great work...
i will read it more later

Hi Damien!
The problem that define only defines a variable in the current lexical
environment. Even if a definition in an if block would work from a syntactical
standpoint, it would be pointless.
As per r6rs, internal (define ...) are akin to letrec, but are only allowed in
definition context.

i was trying to make macro that set! variable if they exist or create it
before if the variable is not defined (tested by the Guile procedure
'defined?' which is not R*RS in any version)
but it

Thank you for the clarification!

Oh, my version is an error. I implemented the macro before definitions in

Andy did a marvellous thing implementinf the new letrec: if it is possible,
letrec will have no overhead. It also automatically handle dependant clauses:

I’m not sure which approach I prefer. Your approach is mo
Note however, that I seem to have forgotten when and unless. also: cond has no
support for the extended "test guard => lambda" form. Neither do I believe that
the any "special" case form is supported. If there is any interest whatsoever,
I can implement it when I have time.
The code produced is
I implemented this hack before guile 3 got defines in function bodies:
https://hg.sr.ht/~bjoli/guile-define
Even I guile 3 it allows a more liberal placement of define, but it won't work
for things like bodies of imported macros (like match)
