I don't know about difficult to type. I type things like that quite
frequently.

As for (a lot of) thinking, well, I find that most of vim's power
requires some thinking.

Unless I had a reason not to, I'd likely use %s/^\s\+// and apply it to
the entire buffer.

I find that repeating commands gets tedious quite quickly. Especially
if you're munging data. Hence why I like regular expressions like the
one above, or macros (possibly of the recursive variety). Why should I
have to mentally execute the test to see if I need to apply the action
to the line when I can have the computer do it for me. I just need to
tell the computer what to do.

IMHO regular expressions and and macros lend themselves to more
automation. It might even be possible to move the regular expression to
a (s)ed script.
