[erlang-questions] Any Erlang Devs Contemplating Elixir?

Don't forget #m(...) for literal maps and #"..." for utf-8 encoded binary
strings.

Actually they are all well-defined. The #(...), #b(...) #m(...) define data
types based on the CL syntax for vectors #(...). The others are also taken
from standard CL.

If you want to add these datatypes and constructs, which I do, then you are
going to add new syntax however you do it. Also these are all literal
values and not forms. It is the forms being extremely consistent which make
writing macros very simple. It also allows you to generate "new" syntax
which Elixir does not.
