Re: PDD: Conventions and Guidelines for Perl Source Code

[Dave Mitchell]

Since we all seem to be agreed that macros that Do Strange Things are evil,
but are a necessary evil in certain extensibility situations,
and since Larry choked on my choice of naming scheme for macros
which declare variables for you, here's a slighly more modest proposal:

=item *

A macro that may declare stuff and thus needs to be at the start of a block
should be prefixed with C<DECL_>, eg C<DECL_SAVE_STACK>


So dSP would now be DECL_SP. And we dont specially mark macros which may
use impicitly declared variables ???
