This has benefits all round: code factoring for parse/compile/execute, proper context save/restore for exec, allow to sepcify globals/locals for eval, and reduced ROM usage by >100 bytes on stmhal and unix. Also, the call to mp_parse_compile_execute is tail call optimised for the import code, so it doesn't increase stack memory usage.
