“abcd”.slice(10) raises IndexError, so should “abcd”.slice!(/x/),
I thought.

So what about “abcd”.slice!(‘x’), “abcd”[‘x’] = ‘y’, “abcd”[/x/] = ‘y’
and finally “abcd”.sub!(/x/, ‘y’)? They all don’t raise exceptions.
I don’t say that they all should but that it’s somewhat inconsistent.

The first three should raise exceptions. I will fix.

The last one “abcd”.sub!(/x/, ‘y’) should not, because its behavior is
“to replace the first occurrence of x if any”.
