1. you use q[ ... ] with symbols [ and ] in there. Why does that not cause a syntax error?

    For the why I can only answer with a generic: because Perl's parser is (mostly :) well thought out and implemented.

    I assume that the parser must be doing a maximal munch at that point.

    The 'balanced quoting' facilities of Perl are one (of many) things that I really miss in other languages. They save so much mess & hassle with escaping stuff.

    Mind you, I abhor their overuse in Perl--eg. q[] instead of a simple ''--almost as much as I miss them when they aren't available.

  2. And what does that #' comment at the line end mean to you?

    That's simply a crutch for my editor's less capable syntax highlighting parser. It see's the single quote embedded in the construct and starts highlighting the following text as a string constant, but doesn't stop until it sees a second single quote.

    The comment prevents that erroneous highlighting from running on to subsequent lines.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
