For the record: I do that as well for some of my libraries. But I 
usually strip prefixes because I use `modulename.typename` for 
`luaL_newmetatable()` to minimize conflicts and I want to keep the 
output of `__tostring` significantly smaller than the length of a 
terminal line.

Lua file handles currently use "file (0xdeadbeef)" (i.e. no colon but 
extra parentheses). So that would be "fixed" as a bonus ...
