If I want to have a method taking a callback function, I have to specify
if it should take a function or delegate even if I don't really care.
What's the best way to accept either? I cannot see any wrapper for
something like this in std.typecons.
The simple way:
void callback(int i, void delegate(int) dg)
{
dg(i);
}
void callback(int i, void function(int) fn)
{
void wrap(int j)
{
function(j);
}
callback(i, &wrap);
}
And of course, wrap should be calling fn(j), not function(j)!
