foo("123") means "call the callable identifed by the expression 'foo' with
foo with the string '123'", so that's just what should happen.

received by whom?  if you call a function with an argument, the function
receives the argument.  the expression used to locate the callable (in this
case, the function name) is not part of the call.

no (at least not given how you've described your problem).
