in reply to proxying overloads: returns seem to lie

I took a look at the code, and added

print "*** ($capsule) *** Result: ($result)\n";
to the code. When I ran the code, I got
# capsule overload eval-ing : ${$_[0]} eq $_[1] # capsule overload returning: 1 *** (It's a widget!) *** Result: () # result of comparison: false
which seems to mean that the eq has failed. However, when I replace eq with =~, the code appears to work as you expected; however, then it appears to bypass the nomethod overload.
*** (It's a widget!) *** Result: (1) # result of comparison: true # result of comparison: false

Likewise with substituting !~ for ne.

Wish I could be of more help,

Update 1:
It appears as if nomethod fails to return anything even when hardcoded. I probably need to do more research.

Update 2:
It looks like Capsule is looking for a nomethod in Widget, but failing to find that, invokes Capsule's nomethod. However, it appears to toss the value in what looks like a return through Widget. It should probably be run through the perl debugger will full tracing.

Sorry again,
"Perl. There is no substitute."
