Re: Optional Subroutine Arguments Like in "print FILEHANDLE LIST"

> I would like to create my own subroutines which would work the same way as print FILEHANDLE LIST works.

That's actually just another syntax for FILEHANDLE->print(LIST) a.k.a. "indirect method call".

So creating your own methods would do and

a bareword OTHER_QUEUE must be a package
a var $other_queue hold an object or a class-name (= package).

But are you sure you wanna go such exotic ways for just a little syntactic sugar?

IMHO it's better to simply write

queue other => $job;

and checking if queue() had 1 or 2 args.

are you sure you wanna go such exotic ways for just a little syntactic sugar? Agreed. I certainly wouldn't embrace barewords when defining a new module's interface, as described in more detail at: Re: Indirect Object Syntax (Parsing Barewords and Quoting References)	[reply]

That's actually just another syntax for FILEHANDLE->print(LIST) a.k.a. "indirect method call". It's not. `print`, as an operator, can have whatever syntax it wants. And while `print FH ...` looks like an indirect method call, it's not. It's simply the `print` function/op. This means it doesn't call the `print` of IO::File or whatever package `FH{IO}` is blessed into like `FH->print( ... )` does. But are you sure you wanna go such exotic ways for just a little syntactic sugar?* Note that indirect method calls are disabled in v5.36 of the language (i.e. when you use `use v5.36;`). It's not the time start using them!	[reply] [d/l] [select]

I seem to remember that I was able to overide `say` in this way, but I can't find the thread anymore. Cheers Rolf _{(addicted to the 𐍀𐌴𐍂𐌻 Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]
