Thank you very much for your research!

I think illegal names are mostly a problem of the output and/or input, and not of this module, but that is also why I want to move away from producing strings as output myself.

I'm a bit wary of pulling in the prerequisites of SQL::Translator, for what should be fairly simple functionality. In the long run, maybe the module should just produce a data structure that SQL::Translator can consume. Most likely, that would be something duck-typed to what SQL::Translator::Parser::JSON produces... SQL::Translator::Schema::Field looks like a good target/output interface though!

From your discussion of names, I think Guess or Infer should be a relevant keyword, and Data and Type are also very relevant. Names are hard :-/
