My understanding is that it was mostly a /(counter)?cultural/ decision, to 
make dangling-else syndrome impossible. For the same reason "else if" is 
spelled "elsif", so there doesn't have to be a special braceless exception 
for "else".

It might also be wise to note that if your statement is really that simple and 
important, you might be better off writing "statement if condition".

Yes, I know that I'm diverting rather than strictly answering. My personal 
opinion is that I can live with it, because I've shot myself in that 
particular foot before, and that there are good reasons. My other opinion is 
that I wouldn't mind if a particular rule in the grammar could be enabled / 
disabled with "use strict 'braces'" either, as it is somewhat unperlish to 
prevent footshooting for that sake alone.
