It could be just me though. > > I think I like =~= best. i like having the equals on the inside because it will allow us to add less than, greater than, and not equals in the future (or whenever). i also like the visual of [=] because it focuses the attention on the equals rather than obfuscating the code (as I feel =~= does). here's some code to illustrate these: if ($zeev [=] $andi) ... if ($jim =~= $rasmus + $caffeine) ... while ($php3[$n] [<] $php4[$n]) ... yuck - how do we handle !=== ? is it !=~!= or =!~= ? of course: if ($zeev->choice [!=] "[=]") ... ^^^ hrmm... what does the parser think about that space? for ($i = 0; $i !=:= count($developers); $i++) ... if ($i <:< $j) ... if ($deadhorse =:= $beat_to_death) exit; i would assume that the <, >, and != should all be part of this. this assumption is based on another assumption that these expressions should be quicker than the standard =, <, >, != because no type conversion is necessary before the comparison. -brian-
