Yes and no.

Yes, there would be DSLs, just as there are some simple ones right
now. For example, the list in the -export attribute is not a proper
Erlang term and can be seen as a DSL. Type specifications definitely
are DSLs. Edoc too.

No, in that post I wasn't advocating user defined DSLs. Only their use
in "standard" places instead of worse alternatives.

Regarding metaprogramming in Erlang, it's another issue completely.
For some years ago I submitted a proposal in the form of an EEP, but
was met with a wall of silence
(http://www.erlang.org/cgi-bin/ezmlm-cgi/5/010) and I got sidetracked
on other projects.
