[erlang-questions] noob namespace question

[Rustom Mody]

In Erlang variables start with a capital letter, atoms start with a
lowercase letter.
Functions also start with lowercase.

How does Erlang distinguish atoms and functions? Especially in the context
of higher order functions.?

[Disclaimer: noob to Erlang but not functional programming or Lisp.  Erlang
atoms look quite close to Lisp atoms though also different...]
