: test ['] recurse ; ' recurse test . . 140485567108688 140485567108688  ok

So what's the problem?

The interpretation semantics of RECURSE is by the standard undefined.  It 
does execute the last definition in current git Gforth.

I accept that if a word can be [']-ed, it also can be '-ed, and the 
interpretation semantics is identical to ' it and EXECUTE that.  All those 
conditions are met here.  RECURSE is just an alias to the current/last 
definition.
