Not much about it in my notes :) Re: Compact data classes, Re^2: return of hash-assigment in list context (bug?), Re: lvalue XS subs, lvalues and action at distance, Re: lhs substr(): refs vs. scalars, Re^2: Working with fixed length files
Seems, if you're parsing fixed with records with substr, use it
If you're making an object system/builder, maybe use it sometimes if you're used to c way of doing things :) ( Object::Tiny::Lvalue .... )
Otherwise don't use it
