I think you might just be using the wrong kind of function.
---
import std.stdio;
// the helper does the setup then calls another function for
specific stuff
void helper(void delegate(ref int) specialized) {
// setup stuff
int x;
scope(exit) writeln("exit ", x);
// specialized stuff abstracted out
specialized(x);
}
void foo() {
helper( (ref x) {
x = 34;
});
}
void main() {
foo();
}

Yeah, this should work. Was hoping there was just a simple way to
pull the code out but I guess this provides the best alternative.
Thanks.
