Selectors with underscores

There are different use cases, three of the most known:

a) ORM (GLORP, ...)
Mapping column names (which may have underscores) to methods

b) External stuff (FFI, C-Mapping)
Callbacks with the same name as C-functions (with underscores), ...

c) Mapping of files to methods
Seaside for instance maps file resources (CSS, images,
javascripts, ... who can have underscores in filenames)
either external (Apache, ...) or in-image as methods in
subclasses of WAFileLibrary

...

Agree, procedure was a bit restrictive. Say external blob :)

DBus calls is where I last encountered them. CamelCase methods can be called transparently, but for selectors with underscores I had to resort to #dbusPerform:. Actually, for those cases I'd wish for Croquet's positional arg support ... (ducks and runs)
