Keep on dreaming. It'll break every single script I ever wrote and will write.
It's like telling me that in order to have my car drive on the correct side
of the road, I have to sit on the backseat of my car.

I, nor the guys I programmed with on high-school, not my colleages fall in
this group. I've always known I am not everyone, but to rule me (and all that
think like me in this respect) out to be able to drop parens on if statements
is ridiculous.

So were the spaces in cobol and so are they in python.
I'll stick with perl5. Is is an absolute show stopper for me.
And I am not kidding.

Ugly. Should be a space

Makes me laugh.

So is sqrt( 9 )

Exactly. And perl(5) has always left us free in choosing style and layout.
FWIW So has C in many aspects
