Literals work awfully with the dot notation

The parser has trouble using literals with the dot notation

The following
```haskell
main: -> 1.print()
```
Is parsed as 
```haskell
main: -> 1.0(print())
```

There is trouble with Float64 particularly as it produce a hard parse error:
```haskell
main: -> 2.2.print()
```

The `Bool` and `String` work well. The problem is obviously when parsing the dot `.`
