toDelegate

fnauto toDelegate(F)(auto ref F fp) if (isCallable!(F))

Convert a callable to a delegate with the same parameter list and return type, avoiding heap allocations and use of auxiliary storage.

Parameters

`fp`	a function pointer or an aggregate type with `opCall` defined.

Returns

A delegate with the context pointer pointing to nothing.

Example:

void doStuff() {
    writeln("Hello, world.");
}

void runDelegate(void delegate() myDelegate) {
    myDelegate();
}

auto delegateToPass = toDelegate(&doStuff);
runDelegate(delegateToPass);  // Calls doStuff, prints "Hello, world."

BUGS:

Ignores C-style / D-style variadic arguments.
