[HerrCai0907]

fix error report of code:

function foo<T>(fn: () => T): void {
  trace(nameof<T>());
}
foo((): string => ""); // Type argument expected.

Can you explain in a few sentences what this change does exactly? I'm probably just missing it, but I'm not quite seeing which limit was removed.

[HerrCai0907]

@dcodeIO limit is parameterTypes.length == parameterNodes.length. But actually function can receive a callback which parameter count less than signature parameter count. So this limit can be removed.
