Hi,

It looks like constexpr-based compile-time parsers can be integrated 
into TMP-based ones (like Metaparse). I've created an example parser 
parsing a*b*a* in a way that the a* parts are parsed using TMP while b* 
in the middle is parsed using a constexpr function. Here is the code: 
https://github.com/sabel83/mpllibs/tree/master/libs/metaparse/example/constexpr_parser

Parsers based on constexpr can return values only while parsers based on 
TMP can return types (typelists, metafunction classes, etc). Based on 
the above example parts of the TMP-based parsers could be implemented 
using constexpr - a lexer for example? (just an idea)

Regards,
