That means that you within your repository (next to .hgsub) have a bool 
directory (the left hand side) which actually is a hg repository 
(bool/.hg already exists). When you push and pull the subrepository it 
will happen to an url with the path ../bool (the right hand side) 
relative to the location of where the top level goes.

I recommend that subrepositories always are used with trivial mappings 
such as "bool = bool".

So it is a "next to repository"? Then it is not a subrepository.

If you really need these two repositories next to each other then I 
suggest you create a new top level repository that has these two 
repositories as immediate subrepositories.

I doubt that.

It is not so much a limitation but rather a definition: subrepositories 
are repositories in a directory below the top level repository which 
references it in .hgsub. That ensures both security and simplicity and 
that subrepos are managable.
