perlquestion muba After having written a couple of programs in a not very well known programming language that usually employs a style of <c>some_variable && some_subroutine()</c> to run a subroutine only when some_variable holds a true value, I find myself doing the same in Perl often lately. But then I realised that Perl also has the <c>some_subroutine if $some_variable</c> syntax, and of course the filled with line noise version, <c>if ($some_variable) { some_subroutine }</c>. All of these have pros and cons, I think. <readmore> One <c>$var && subroutine</c>: this one follows the way you formulate logic propositions: it is immediately apparent that subroutine() is only called when $var is true. However, readability might suffer a bit as it appears a bit "cryptic", especially compared to snippet two Two <c>subroutine if $var</c>: flows like natural language, woohoo! However, the fact that subroutine() is called when $var is true is only revealed at the end of the statement. Three <c>if ($var) { subroutine }</c>: has the advantage of snippet one (condition first, consequence next), but is filled with line noise. <c>( ) { }</c> just for a really simple 'IF this THEN that' kind of construction. </readmore> Obviously, the TIMTOWTDI principle applies here but what I've come to ask is which of these styles do you prefer, and why? Just out of curiousity.
