If we removed the requirement for the ampersand, along with
requiring parentheses for non-property functions, code which
expected to call the function without parentheses would
silently compile, but not do what was intended.
Consider this...
float handleRequest() {
return 1.0f;
}
float x = handleRequest; //compilation error
or
auto x = handleRequest;
writefln("%f", x); //compilation error
I think we'd get a compile time error for most cases without
significant changes to the compiler. But the edge cases if any
can probably be detected at compile time with modifications to
the compiler.
Here is an edge case (for reference)...
writefln(x);// will now print the address of the function
