Is there a language-independent name for the symbol between a Map key and value?

Question

I.e. is there a generic name for the : in Groovy's ['a':'1'], => in Ruby's {:a => '1'}, -> in Scala's Map('a'->'1')?

Answer 1

It appears there is no universally accepted term for this symbol, although there are a few variants with some traction listed in the other answers.
