Title: REPL Floating Point bugfix

In JS, the expression ".1" is a floating point number. Issue 4268 concerns the
REPL interpreting floating point numbers that lead with a "." as keywords. The
original bugfix worked for this specific case but not for the general case:

var x = [
.1,
.2,
.3
];

The attached change and test (`.1+.1` should be `.2`) fix the bug.
