Would a reference serve your purpose, or is there something in the
input-context you wish to preserve?

What would happen if the originating module was reloaded with a modified
version? Will the old version of the code still remain resident until
the fun returns home to execute? I suspect that the code loading logic
may not know about the itinerant fun. The results may be undetermined.

I'm curious to know because I tend to use funs where, upon reflection,
simpler data types would suffice with less potential unanticipated
results, and more potential to expand capability, because fewer usage
assumptions are made too early.

P.s. I feel the caffeine effect...
