No, it's not. Just because dialyzer does its analysis on Core Erlang, 
this does not mean that it was ever designed to analyze languages other 
than Erlang.

I grant you that dialyzer's analysis is in principle applicable to other 
languages that compile to Core Erlang, but I think that my previous mail 
makes it clear that I also think that the responsibility for doing any 
changes that are required lies with the developers of languages who are 
interested in having such a tool for their language.

It's probably irrational to expect that non-users of a language care 
about the tools that are available for it more than the community of 
that language, isn't it?
