I'm in two minds about this.
On the one hand, null elision breaks the principle of least surprise —
both in reference to other programming languages, and in reference to
SH_WORD_SPLIT's default behaviour being the unlike-Bourne-shell
behaviour.
On the other hand, making it on by default would be backwards
incompatible, and making it off by default would mean there's yet
another syntax-changing option for everyone to keep in mind when they
review random autoloaded functions' code.
All in all, perhaps this is a change to keep in mind for 6.0 (deferring
it to a major version due to the incompatibility).
Thoughts?
Cheers,
Daniel
