in reply to Re^3: Operator precedence
in thread Operator precedence

I do feel I am a seasoned perl programmer myself, but in this example, that B::Deparse only confuses me. Who would ever write

banana  or cherry  if apple ;

to make things clear? I would NEVER use that construct. The give construct by the OP causes no mental parsing problems whatsoever.

    I wasn't advocating it, I was just amused by it :)

    That said, I think the terms confuse things because they mean nothing, How about:

    open( FH, '<', $ARGV[ 2 ] ) or die( "$! : $ARGV[ 2 ]" ) if $ARGV[ 2 ];

    Or:

    eval $code or die $@ if $code;

    Doesn't seem so uncommon once you substitute realistic terms.

      All evenly confusing, as my mind hates statement modifiers. I try to prevent using them as long as possible. To me statement if expression; reads as utter crap. I prefer reading expression and statement;. YMMV. I completely realize not all our minds work the same, so any other reader might be confused the other way round. Mixing these will hurt both.

      The only statement modifier I am comfortable with is for in simple expressions like s{\s+$}{} for @foo;.

        Hm. I find 'Pick up a bottle of duty free Scotch if you have time' and 'If you have time, pick up a bottle of duty free Scotch' completely interchangeable.

        And 'beat the egg whites until they form soft peaks', infinitely preferable to 'until they form soft peaks; beat the egg whites';
