Just because mathematics allows an implied multiplication doesn't mean Raku
does -- in fact I can't think of any programming language which does. You
need to stick an explicit multiplication operator ('*' or '×') between the
5 and the left parenthesis.
The reason for the error message is that adding parentheses after something
is interpreted as trying to invoke a function. Callable objects such as
functions have a CALL-ME method which is what is invoked to call the
function. An integer lacks such a method, since it isn't callable.
