quote for the most part isn't necessary, since atoms aren't evaluated -
they represent just themselves and not some other value.
(define Var 'value)
just translates as
Var = value.
If you are finding it necessary to create atoms that do not conform to
the normal atom naming rules (starts with lowercase, no funny
characters), you can use '' to create such a nonstandard atom.
Var = 'Some weird atom'.
quasiquote/unquote I'm less certain of due to my lack of scheme
experience, but again since erlang doesn't evaluate every term it
doesn't seem like it is needed.
(define Var 'world)
is roughly the same as
Var = world,
I suspect ` is used by schemers for much more complex and powerful
constructs, but without seeing the use its hard to say how to translate it.
