Say anything about efficiency never did I. :-) I was merely commenting
on a personal preference based largely on my perspective as a native
speaker of (US) English. Now - if I WERE to address efficiency, I
don't find "Yoda speak" to be any more efficient. It's usually the
same words just in a different order. What's more that order, while
quite natural for some languages, is not natural to me at all. As Bob
mentioned, it requires a little extra thought for my brain to push
certain phrases onto the mental stack before I can pop them off in an
order that "makes sense." In programming terms, any code that requires
the same amount of statements but requires more cycles to process is
not what I would consider more efficient.
As far as the programming practice that Colin was advocating, it is
not a bad habit. And as far as the computer is concerned, the
efficiency is a wash since the number of internal steps probably
doesn't change much. However, it doesn't always work. (I know - no one
claimed it did.)
