... and we have not that bad mapping type after all - lookup time is ~ the same as in one-attr instance. My namedtuple implementation on the other hand degrades awfully. So, need to rework it. First observation is that named tuple fields are accessed as attributes, so all names are interned at the program start. Then, really should store field array as qstr[], and do quick 32/64 bit scan thru it.
This directory contains tests for various functionality areas of MicroPython. To run all stable tests, run "run-tests" script in this directory. Note that bytecode tests are not yet stable and should be run separately in "bytecode" subdirectory. When creating new tests, anything that relies on float support should go in the float/ subdirectory. Anything that relies on import x, where x is not a built-in module, should go in the import/ subdirectory.
