Documantation of + for arrays

I think this feature (merging arrays with + operator) needs more documentation. I did not find any word about this in -operators page -array type page -array functions page The only documentation I found is in notes for array_merge. I suggest adding description of this feature to one of the three sections and provide links in the other two where it logically belongs. It is possible that the use of + with arrays is already documented somewhere but I was unable to find it. Then adding links to the above three sections could help. hramrach@centrum.cz
