Bald Eagle is exactly right as to why this isn't working, BTW.
For function{} there is a separate function parser that is pretty restrictive,
and it will not support calling things like bitwise_xor(), trace(), etc. It only
supports numerical values, operators, variables/parameters, and references to
other defined function names. So for this to work, someone would need to define
a "built-in" f_bitwise_xor function (for example), that you could then call in
function blocks.

You would indeed need to "roll your own" using only operators and simple
variables.
