I completely disagree with this type of approach. One should always code in an efficient way, e.g. suppressing return codes, DIMming variables, and so on. It might not make a difference in a 20-line script, however, if you have to write/test/debug/redesign 100+ (1000+, 10000+) lines of code, then those things make a huge impact/difference.
