env: Adjust the load() method to return an error
The load() methods have inconsistent behaviour on error. Some of them load
an empty default environment. Some load an environment containing an error
message. Others do nothing.
As a step in the right direction, have the method return an error code.
Then the caller could handle this itself in a consistent way.
