I have 2 small questions.
1. Is there any reason to exclude underscore as the first char of a dollar quoting delimiter (after the $), e.g. $_foo_$? I'm happy either way, just want to be as liberal as is reasonable.
2. David Fetter asked me the other day if there was any limit on the length of the foo inside the $foo$. I glibly told him that I thought that we should treat it the same as identifiers, but I have pretty much convinced myself that this is wrong. The reason for having limits on identifier length is for our convenience, not to protect programmers from doing silly things, ISTM. There are places in the code where we put names in statically sized buffers etc. with the size set to NAMEDATALEN. Changing this would be far more trouble than it is worth, even if it were possible. However, none of this applies in the case of $foo$, which in fact never makes it outside the lexer at all - the lexer just returns the contents as another string. Truncating the delimiter would actually make doing sane lexical recognition substantially harder, and Tom's original POC patch didn't contain any limit, so I'm intending not to place any limit. Does this seem OK?
cheers
