Almost for sure a version "problem"

Way back in PHP/FI (aka PHP 2) you could use "+" to concatenate strings, I
do believe.

And, probably, somewhere along the way, you could use "+" to merge arrays
or something.

Both probably seemed like Good Ideas (tm) at the time...

Don't do it.

Overloading operators in "cute" ways like that invariably leads to more
problems than the dubious benefit of their usage.
