my is language construct. Just like if, while and return that can be
followed by parenthesis, but aren't functions.

Functions and operators are the same. It's just that what is labelled
an operator usually takes a fixed number of arguments, often consists
of non-alphanumerical characters and unlike what's labelled a function,
is often not prefix. But that's only syntactic sugar (and vinegar due
to precedence tables).
