In the context of our work on syntactic extensibility, we have
implemented a declarative and extensible mechanism to specify and
implement layout rules.
I am looking for background material on how GHC and other Haskell
compilers implement the layout rule. Are there any papers,
documentation, commentary, etc. that discus the actual implementation
of this rule (even if only a paragraph or two)?
I've already looked at the parsing code in GHC and
I have made some improvements to the algorithm, and I am happy to say
that with some minor tweaks, it correctly lays out the programs in the
nofib suite.
the algorithm is not much more complicated than the current one in the
report, but doesn't have the parse-error rule. it does require a single

This is no longer happening, so I guess I ran afoul of a bug.

Well... they are quite useful for lining things up if you're using a
proportional font, and I don't think proportionally-spaced code is a bad
idea. I want them to be optional. But it would be nice if parsers

Multi line comments are nice for commenting out blocks of code.
They're also nice for comments within a line. E.g. haskell-src-exts contains
the declaration
