Hi,
Is there a way to get fluid-let for Guile? Or something like
<http://everything2.com/title/Teach+Yourself+Scheme%253A+5.2+fluid-let>?
I am having a mutable hash object that I don't want to pass as an
argument to every single function that I call, I'd prefer to use a
similar solution to what the ports do, by redefining the default input
port "semi-globally".
I saw this: <http://paste.lisp.org/display/28213> but it does not work
with mutating the fluids.
regards,
Marek

Guile has fluids and ‘with-fluids’, which is similar to what you want
(info "(guile) Fluids and Dynamic States"). It also has SRFI-39
parameter objects (info "(guile) SRFI-39").
Hope this helps,
Ludo’.

Oh, SRFI-39 looks exactly what I was looking for. Now my code looks way
better, more DSLish. Thanks a lot!
