Precisely. There ain't no such thing as "hash context". It simply returns a
list with an even number of elements. Now, when you put that into a hash, the
Right Thing happens.
And it isn't *that* slow; it uses a table, just like the ordinary way tr/a/b/
operates. That doesn't use a hash! Besides, you pay for what you get: if you
want to use this, it'll do all the work for you at *perhaps* a slight speed
expense. But it's sure faster than doing n different counts and assigns...
