Can a simple a==b 'hang' in and endless loop?

[Fuzzyman]

Ok... so I'm now assuming that the information about '==' provided by
the above gentleman *and* that I understand it correctly.

The only confusion in C (which doesn't have classes) is that two list
(like) objects can't be tested by value - only identity.

In Java, comparing strings using '==' compares for identity not
equality (IIUC), giving *plenty* of room for confusion.

All the best,
