        }

        # Print our lines, but first reverse them, but first convert
        # them into upper case.

        while (<>) {
                print;
        } butfirst {
                $_ = reverse $_;
        } butfirst {
                $_ = uc $_;
        }

DESCRIPTION

Acme::ButFirst allows you to execute a block of code, but first do something else. Perfect for when you wish to add to the start of a long block of code, but don't have the energy to scroll upwards in your editor.

Acme::ButFirst recognises both butfirst and but first as keywords.

Usage of Acme::ButFirst is lexically scoped. ButFirstification can be explicitly disabled by using no Acme::ButFirst.

BUGS
