Implementing the recent changes to Varvara in Oquonie, I noticed how many single-purpose labels I used merely to hop over short lengths of code, enough that having ran out of ideas for names to called them, I would default to like &skip, &ok, or &continue. The solution was to create anonymous labels, and as to be capable of nesting them, I ended up inadvertently adding lambdas to Uxntal.
Just stumbled on "Adding Lambda Expressions to #Forth"

Too little too late.
