in thread most efficient regex to delete duplicate words

I always perfer: 

1 while (EXPR)

[download]

instead of:

while (EXPR) {}

[download]

Simply because the '1 while' sticks out at the front where as the empty {} tends to get lost. I find that '1 while' immediately flags this perl idiom and makes it easier for me to pick it out.

    1 while (EXPR): will also avoid the slight over head of entering and exiting the lexical context created by the BLOCK in while (EXPR) {} Perl might be smart enough to optimise the out the empty block though.
