String.toInt() raises IllegalArgument if the string starts with a zero

[sanderginn]

Not sure if this intended behaviour.

toInt("059215102311135031132");
|plugin://rascal/src/org/rascalmpl/library/String.rsc|(9689,431,<414,0>,<434,52>): IllegalArgument()
        at *** somewhere ***(|plugin://rascal/src/org/rascalmpl/library/String.rsc|(9689,431,<414,0>,<434,52>))
        at toInt(|prompt:///|(6,23,<1,6>,<1,29>))


rascal>toInt("59215102311135031132");
int: 59215102311135031132

The error message could definitely be better, but this occurs because the number is given in octal (starts with a 0) but contains illegal digits (the 9). For instance, this works fine:

rascal>toInt("057215102311135031132");
int: 851642288897798746
