how to avoid leading white spaces

[rusi]

For any significant language feature (take recursion for example)
there are these issues:

1. Ease of reading/skimming (other's) code
2. Ease of writing/designing one's own
3. Learning curve
4. Costs/payoffs (eg efficiency, succinctness) of use
5. Debug-ability

I'll start with 3.
When someone of Kernighan's calibre (thanks for the link BTW) says
that he found recursion difficult it could mean either that Kernighan
is a stupid guy -- unlikely considering his other achievements. Or
that C is not optimal (as compared to lisp say) for learning
recursion.

Evidently for syntactic, implementation and cultural reasons, Perl
programmers are likely to get (and then overuse) regexes faster than
python programmers.

1 is related but not the same as 3.  Someone with courses in automata,
compilers etc -- standard CS stuff -- is unlikely to find regexes a
problem.  Conversely an intelligent programmer without a CS background
may find them more forbidding.

When I was in school my mother warned me that in college I would have
to undergo a most terrifying course called 'calculus'.

Steven's 'suspicions' make me recall my mother's warning :-)
