Because I was assuming that every expression
started with a literal, calls to `each` were
getting wrapped by a functionCall node with no
functionName, which was subsequently ignored by
the compiler. This removes all of that uselessness
What was happening was that spaces were allowed in
all literals to account for quoted strings, but
this meant that two identifiers in a row would get
parsed as a single literal. This commit sets a
flag to allow whitespace in literals when a quote
is encountered and then unsets that flag at the
next quote.
