I have been working on an LL(1) grammar parser generator for Erlang/LFE. While we have yecc for LALR(1) grammars this isn't suitable for everything. I think there are 2 main problems:

Evaluating dynamic expressions in LFE
Sometimes you need to evaluate a dynamic expression in LFE, one that has been created during the execution of the program. For example, imagine some other process has sent us an LFE expression which we need to evaluate.
