:-) Thanks for the info. I have obviously never slung a line of code in
ruby. That said, *most* programmers indent for readability (though I don't
see any point for a throw-away one-liner on the CLI), I just couldn't
remember if the ruby crowd had adopted some of python's mandates.

Another question: if you don't typically use semicolons then how do you
split a single line of code across multiple lines? Playing with your source
example it seems to generate syntax errors when I introduce newlines between
some words. Seems there's limited intelligence in the ruby parser for these
issues. Ironically, with semi-mandatory semicolons in Perl it allows the
parser to be even less intelligent and still work. Your instruction
boundaries are always clearly marked.
