(**
Retrieving the source code of a contract from its address is costly
because it requires I/Os. For this reason, we put the corresponding
Micheline expression in the cache.
Elaborating a Micheline node into the well-typed script abstract
syntax tree is also a costly operation. The result of this operation
is cached as well.
