character substitutions

[goddenrich]

we would like to use a tool such as importas but would like to enforce that we strip underscores from the alias name.

an example would be for:

import "path/to/some_package/proto/some_proto_name"

to be enforced to be aliased as someprotonamepb.

I don't think this is currently possible with importas. Would this be something that could be supported?
