Matthias Boehm commented on SYSTEMML-954:
-----------------------------------------
thanks for submitting the PR - of course it is handled on validateExpression if
the first and second expressions are constants, otherwise it is handled by the
runtime - all I'm saying is, please be careful not to put a 1 in there if the
values are unknown.
> PyDML's range() needs all 3 arguments

>
> PyDML's range() breaks when called with two arguments, eg. range(1, 10). This
> is at odds with the behavior of Python's range, and of DML's seq() which has
> a default value of 1.0 for the increment argument and thus does not break
> when called, eg, seq(1, 10).
