But each of them knows when to eshew complicated eval-avoidance-schemes, in favour of simplicity.

merlyn See name_to_page() in CGI::Prototype::Hidden, new() in CGI::Prototype::Mecha, type() in File::Finder, the grammer for Inline::Spew.

TheDamian See import() in Attribute::Handlers, import() in Attribute::Types, install_dispatch() in Class::MultiMethods, initialise() & new() in Class::Std... I stopped here with D-Z to go.

Dominus memoize() in Memoize, in Memoize::AnyDBM_File, fill_in() inText::Template, TIEARRAY() in Tie::File.

And before anyone leaps to these authors defense, there is no need. String eval is a tool. Avoiding it where practical is common sense; eshewing at all costs is illogical.

I'm betting that Perl6 will retain string eval in some form.


Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

    I was just going to reply that MJD's HOP also has a few legitimate uses of string eval. As you said it's a tool, a powerful tool, and as such it should be used with great caution.

    I really hope Perl 6 won't drop the string eval, having it IMHO is essential to any dynamic language.
