Inconsistent decimal evaluation

[kaidesu]

When evaluating 0.4 the evaluation is correct. When evaluating 0 . 4 it seems that the evaluator is treating this as a property and panics:

Ghost (1.0-beta.1)
Press Ctrl + C to exit

>> 0.4
0.4
>> 0 . 4
panic: interface conversion: ast.ExpressionNode is *ast.Number, not *ast.Identifier

Interestingly enough, the same thing is a syntax error in python 3:

>>> 0.4
0.4
>>> 0 . 4
  File "<stdin>", line 1
    0 . 4
        ^
SyntaxError: invalid syntax

It's fixed already, you can close this now.
