Given there not much difference, it would probably be better to stick
with the one that does scalar assignment in the case of a single entry.
I've no idea if anyone is still using GLOB_ASSIGN, but they're not
likely to be complaining about efficiency, and if they always want an
array assignment there's an easy way of getting that.
