As a result of the discussions, I'm now reconsidering using Mouse in TB2. Its
interesting, it's not for any of the reasons I thought, but for a distressing
encapsulation breech built into Moose.
The main concern is that the fact that we're using Mouse leaks out. We must
document that we're using Mouse and users must rely on this implementation
detail. Anything wishing to consume a role must use Mouse. Anything wishing
to take full advantage of subclassing must use Mouse.
This is a critical violation of encapsulation. It means TB2 is stuck using
Mouse forever. I look ahead a few years and see that becoming a severe
limitation.
A side issue is the compile time performance. While XS fueled Mouse is the
fastest OO implementation, compile time appears to be most critical to Perl
test suite performance.
So, uhh... I'm going to go do a bad thing.
