There are no references to subs involved in finding methods when it comes to class or object method calling.

Not directly, but method invocation always involves symbol table lookups, which is just what a symref does.

Makeshifts last the longest.

So you've replaced the symbolic lookup of `$sub` by a symbolic lookup of `"can"`, which, if it reaches `UNIVERSAL::can`, results in a symbolic lookup for `$sub`. And now? Makeshifts last the longest.	[reply]
