[chuck-users] Guile C++ wrap

I started to write a bit on a Guile C++ wrap*), and it strike me it may give some inputs on the discussion on giving ChucK functional language capabilities. First, Guile has a conservative GC (meaning that it just tries to collect some pointers, not necessarily all). It makes C++ implementation very simple: you don't have to write operator=() and copy constructors, because normally, when an object is mutated, it is being done using *this = f(*this) where f is a function of the functional language (so normal object referencing just needs to hand over the pointer). But the question is if such a GC can be made without causing timing problems. Then I use templates to do some Haskell style static typing, though C+ + is a bit too limited. But it is fully possible see what kind of syntax might be possible. For example, one can define an increment function using function1 inc = x >>= x + 1 (though I must use a more complicated syntax in the actual code due C+ + and Guile limitations). Here, ">>=" is the lambda, and in math it is the symbol ↦, in ASCII looking like |->. The Haskell-like define-function-by-cases syntax would be something like: function1 inc; inc(x) = x + 1; though it is hard to get it to instantiate properly using C++ templates. But if built into a ChucK parser, that should be no problem. But it seems that the current ChucK syntax might be enhanced with functional language features. Hans *) http://math.su.se/~haberg/guile/
