Whatever word(s) are chosen as an infix operator should reflect such a description. “Extend” and even “increment” do not sound descriptive enough to me.

"increment" is confusing here, but I get it -- you mean the rhs in Allen's <& proposal. Best to use "source" or "src", "increment" suggests ++ and misleads.
I don't think we should use contextual keywords that aren't verbs for a mutating operator.
At this point I think a keyword operator is no better than a built-in method, especially from a built-in module, but even if just Object.extend.
