Which, for me, raises an interesting point.
I have NEVER used printf in Perl! I think that I cam to hate them with such vehemence, ferocity and vitriol in C that my brain now fails to admint their very existence. Do you get the idea that I didn't enjoy my experience writing 'C'? I was actually brainless enough to write a lot of stuff in 'C' during the 80's. I think I know why I have a full head of grey hair now. In fact, it may have been easier to do it in Z80 assembler (I was working with Micromation multi-processor machines with Z-80's, MC6809's or 80186's!)
Maybe I might look at them in Perl? But then maybe not, I like concatenation operators :)
