Re^3: Optimizing non-alphanumeric method calls

> but it cannot be used, unfortunately, on chained method calls, such as $obj->$method_1->$method_2, unless the result returned by $obj->$method_1 is stored somewhere, which I guess it may slow things down quite a bit.

I'm not sure what you mean, $c_method isn't different in this respect to the other approaches you have proposed.

For chained method calls you need to return the object in intermediate calls, no matter which approach you use.

Maybe you should show us some real code to make things clearer.

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);` [download] 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.	[reply] [d/l] [select]

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) Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l] [select]

Maybe you should show us some real code to make things clearer. trizen has done what we ask of nearly every first-time poster. He has prepared a complete executable example. I feel it would be far better to suggest improvements to the example than to discourage this style of question. Bill	[reply]

Nope, his reply to my supposed "discouragement" was much better. But your contribution so far is on another level... Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply]
