OP (OP_OBJC_MSGCALL)
-/* This is EXACTLY like OP_FUNCALL but is semantically different.
- In F77, array subscript expressions, substring expressions and
- function calls are all exactly the same syntactically. They
- may only be disambiguated at runtime. Thus this operator,
- which indicates that we have found something of the form
- <name> ( <stuff> ). */

/* OP_COMPLEX takes a type in the following element, followed by another
OP_COMPLEX, making three exp_elements. It is followed by two double
args, and converts them into a complex number of the given type. */
