float literal and identifier parsed incorrectly

[trueharuu]

Inputs:

let x = 3; 3x
3 x
5y

Expected Outputs:

Syntax Error: Invalid or Unexpected token
Syntax Error: Unexpected identifier 'x'
Syntax Error: Invalid or Unexpected token

Actual Outputs:

3
3
ReferenceError: y is not defined

It seems that (integer)(identifier) is getting parsed as (integer), (identifier), effectively disposing the integer. None of these should pass the lexing stage, except in the case where there is whitespace between the two (both are valid tokens individually)

• 3x and 5y -> dash_lexer
• 3 x (space between) -> dash_parser?
