option to infer .mli files

[UnixJunkie]

Hello,
It could be useful if one could force generation of missing .mli files (.ml file with no corresponding .mli file) upon build.
That would allow tools such as dead_code_analyzer from lexifi (available from OCaml 4.03.0) to be even more useful.
Cf. https://github.com/LexiFi/dead_code_analyzer

this is what the defunct obuild infer was supposed to do already

Can't you add this in a snap Vincent?
Not tired of the lazy Haskell yet? ;)
