Assuming you're ok with breaking every program that does `print $x`, how would you implement IO::Handle::print without the print operator? There are other issues, but they're not worth mentioning after the above two.	[reply] [d/l]

Um, I suppose I'm not sure I see the difference between a method called print, called indirectly, that appears to do the same thing as C<print> the operator. Could you explain the difference to someone to whom it is not obvious? ;-)	[reply]

Without an explicit filehandle, where does the output of `print $x` go? How is Perl to tell the difference between "print the contents of `$_` to the filehandle in `$x`" from "print the contents of `$x` to the currently selected filehandle"?	[reply] [d/l] [select]

So you want me to explains how it's impossible to write the method without the `print` operator? Well, why don't you try it. Or are you asking me to explain why they don't do the same thing? Well, consider `>perl -le"$x = 'abc'; print $x;" abc` [download] As you can see, it doesn't call the method `$x` of class `abc`. If it was an indirect method call, it would have the following outcome: `>perl -le"$x = 'abc'; $x->print;" Can't locate object method "print" via package "abc" (perhaps you forg +ot to load "abc"?) at -e line 1.` [download]	[reply] [d/l] [select]
