Hi all,
there was a discussion in 2006 but w/o a result, and I didn't find any
bugs about implicitely casting functions to delegates. It seems to be
impossible as long as function-pointer calls work differently than
delegate calls in the ABI. Will this at some point be fixed?
If not, is there a conversion function in phobos (I didn't find one)? I
played a bit and found that this one might work:
R delegate(A) funcionToDelegate (R, A...) (R function(A) func)
{
return (A a){ return func(a); };
}

There is actually almost forgotten function in std.functional -
toDelegate, which does it in the most general way, functional objects
covered.
Sadly enough it's not listed in docs, because of the auto return.
