To elaborate: the problem is not with the computation of b's 
initializer (duh, it even prints the result in the error 
message), but attempting to retain an associative array created 
at compile-time for runtime.

There is some progress in this area; as of last release (or maybe 
the one before that?), we are able to transfer class instances 
created at compile-time to runtime. It may take some time before 
we gain the same capability for associatve arrays, because their 
implementation is a tangled mess, but it is a work in progress.
