Among many new things in the recent proposal about adding generic programming for Golang there is a new keyword any
So if my current program has declared a variable named any it won't compile.

Wrong. any will be a predaclared identifier not a keyword.

No, of course not, it will just redeclare any in the current scope.
The list of keywords in Go is pretty short, see https://golang.org/ref/spec#Keywords . Keywords are keywords and cannot be used for other things. A predeclared identifier (see https://golang.org/ref/spec#Predeclared_identifiers) is not a keyword and can be redeclared.
