(I'm assuming that you meant something like "if $y ~~ [..] $x ±
$epsilon {...}", since matching a value to a range that's centered on
that value is tautological.)
Junctions should not return individual values in list context, since
it's possible for one or more of said values to _be_ lists. That
said, I believe that it _is_ possible to ask a Junction to return a
set of its various values (note: set; not list). Still, we're already
at a point where:
if $y ~~ $x within $epsilon {...}
uses the same number of characters and is more legible. _And_ doesn't
have any further complications to resolve.
