parser doesn't handle expressions vs statements properly.

[tef]

In ruby, meth (args).meth2 {block} parses differently to meth(args).meth2 {block}. The whitespace is significant.

For example, in opal, this prints [1], [1], rather than [2], [1] as expected

def p x
  puts x
  x
end

p ([1]).map {|x| x+1} # this should print [2]
p([1]).map {|x| x+1} # this should print [1]

Yeap, looks like a lexing issue. Will make a priority to fix.

iirc, in parse.y this is handled by the use of LPAREN/LPAREN_ARG, which is controlled by the lexer state hack EXPR_*

This should now be fixed on master, by 13ed3c5.
