in reply to Re^3: Optimizing non-alphanumeric method calls
in thread Optimizing non-alphanumeric method calls

Here is a real code translation of "(1+7)/4":

use constant NUM23343688 => Sidef::Types::Number::Number->new('1');
use constant NUM25174720 => Sidef::Types::Number::Number->new('7');
use constant NUM24946728 => Sidef::Types::Number::Number->new('4');

((main::NUM23343688)->${\'+'}(main::NUM25174720))->${\'/'}(main::NUM24
+946728);

Note that currently I'm using the reference-dereference technique for calling non-alphanumeric methods. What I'm really looking for, it's an way to avoid this inefficient approach without any other trade-offs.

    Interesting, I wasn't aware of this trick to fool the parser. (I suppose the special symbols are put directly into the stash of the class)

    Using _add instead of + as method name should make it easier.

    But replacing ${\'+'} with $_add holding the code ref is the fastest.

    Problems with chains do not exist.

    Btw: Are you aware that Perl supports operater overloading?

    (This won't be faster, rather slower but more readable)
