Doesn't seem to work with stringi::stri_trans_general

[fernandovmacedo]

I have tried to run lookup(stringi::stri_trans_general) and the R function is returned correctly
function (str, id) { .Call(C_stri_trans_general, str, id) } but the .Call function source did not appear.

Thank you for opening the issue, I think this is due to stringi using native routine registration, which is currently not handled by lookup. I will look into this in the near future!

So turns out stringi uses a macro in it's native routine registration (https://cran.r-project.org/web/packages/highlight/index.html) which breaks the regular expression lookup uses to find the mapping. I would prefer not to special case packages, so for now stringi is not going to work with lookup.
