The issue is that "combine", which is the function that '+' maps to,
returns an array. When, in the main program, I say:
my @ar = $ca1 + ca2
I expect the "combine" function to be called in list context.
Some hints: you forgot about cryptocontext. What would you think
myMultiplyArgs($ca1 + $ca2, $ca3 + $ca4, $ca5 + $ca6)
would return if your semantic would hold?
Overloading changes IMPLEMENTATION of operations; the SEMANTIC returns
the same.
(If, instead of what I do in the example, I return a reference to the
array, and alter my main routine correspondingly, then, of course,
everything works.)
Enjoy it. ;-)
Hope this helps,
Ilya
