Functional style and instructional style can be mixed, but any opcode inside a
functional style expression has to return exactly one stack slot (most of the opcodes do).
Functional style expressions cannot use instructional style internally, i.e.
``1 2 mstore(0x80, add)`` is not valid assembly, it has to be written as
``mstore(0x80, add(2, 1))``. For opcodes that do not take arguments, the
parentheses can be omitted.
Note that the order of arguments is reversed in functional-style as opposed to the instruction-style
way. If you use functional-style, the first argument will end up on the stack top.
