Python

You all act as if you hate it, but we all know it's your favourite language and you're just trolling so that other people won't learn it and see its brilliance.

You guys clearly don't program in Python regularly.  An age-old trick which I use fondly is to use * instead of indentation.

def A(x):
*if x == 0:
**B()
**C()
*else:
**D(x)
**F(x - 1)

I then use "Astritab", a program I made myself in Python, to go through and parse all the * into tabs.  I then feed that file to the compiler.  It definitely makes it easy to save horizontal screen real-estate.
