Hi Phil -

Did you see Christophe's eUML2 frontend for MSM that uses Metaparse?

<https://htmlpreview.github.io/?https://raw.githubusercontent.com/boostorg/msm/msm3/doc/HTML/ch03s05.html>

the code is very readable (for example):

<https://github.com/boostorg/msm/blob/euml2/include/boost/msm/front/euml2/stt_grammar.hpp>

<https://github.com/boostorg/msm/blob/euml2/include/boost/msm/front/euml2/state_internal.hpp>

I had the same question and found the eUML2 frontend to be a compelling 
example of "real world" usefulness. I'm currently thinking about a 
Spirit X3 front end that allows proper "operators" for PEG grammars.
