--- Comment #2 from Eyal <e...@weka.io> ---
I see, but this would not be a problem if function was automatically
convertible to delegate (std.functional : toDelegate).
Is there any reason that you cannot hand over functions when delegates are
expected?
I'd expect something even simpler than std.functional:toDelegate to work,
especially if done inside the compiler:
auto toDelegate(R, Args...)(R function(Args args) func) {
struct delegate_t {
R function(Args args) ctx;
R function(R function(Args args), Args args) func;
}
static R call_func(R function(Args args) arg, Args args) {
auto f = arg;
return f(args);
}
auto del = delegate_t(func, &call_func);
return *cast(R delegate(Args) *)&del;
}
