ABSTRACT

Simpify syntax of do BLOCK by deleting do before the block and ; after it.

DESCRIPTION

One of the most common mistakes I make is forgetting a ; after do BLOCK, probably because I'm thinking ``if'' and an if doesn't require a : after it's closing }. I'll type, for example,

    $cond  and  do  {
        # statements
    }

instead of

    $cond  and  do  {
        # statements
    };

Can the syntax be simplified to drop the ;, and while you're at it, how about the do also, so one can type

    $cond  and  {
        # statements
    }

If the do and ; are redundant should they be eliminated to obey the rule:

    Omit redundant punctuation as long as clarity doesn't suffer.

IMPLEMENTATION

Unknown.
