It would be consistent with let/var if you could write a comma-separated list of typealiases in one declaration, e.g.:

typealias Tomayto = Tomahto, Potayto = Potahto

i am willing to pick it up...
can anyone point me around how the codebase is structured ? and where is type alias parsing code ?

@progressive-galib You may want to bring this up to the community on the Swift forums first. The parser lives in lib/Parse.

I got busy and couldn’t continue, but I finally have some time to finish this up.

i posted in swift forums Is Allowing Multiple Type aliases in a Single Declaration for consistency let and var declarations a good idea (or SR-5528)
