For loops accept non-integer values #54

For example, this works...

For i = "a" To "z"
  Print i
Next i

... but only prints "a", indicating that if this feature was intended, it at least doesn't work. It could be a nice feature, though.

Funny, this does not work:

For i = False To True
  Print i
Next i

Because, Toistorakenteen askeleen ja iteraattorin tyyppien on oltava samat. Why are False and True called a step and an iterator? They whould be called an initial value and a final value.

As True and False are both booleans, the error message appears to be completely misleading.

Also, Print(Boolean) isn't declared.

This is not intended feature and is a bug. Thank you for reporting.

fergusq: The error message is all right though not the most iformative one. The message comes from the fact that step defaults to 1 which is not castable to boolean. In the original code number is castable to string so no error is raised.

As soon as we can get our new compiler working this bug should also be fixed.

Ps. Boolean to String casting is implemented in dev version and is waiting to be pulled to master.
