Rules do not. (A view is just a rule anyway.)
Functions do, but that's because their definition is entered as a text
string, which leads directly to those quoting headaches that you're
all too familiar with.
I've thought occasionally about improving the lexer so that parsetree
nodes could be tagged with the section of the source text they were
built from (probably in the form of a (start offset, end offset) pair).
This was mainly for use in improving error reporting in the
parse-analysis phase, but it might be useful for storing original source
text for rules too.
