There are some knows bugs in class BIT (do not report these please,
except when you cannot work around the problem).
Exceptions, rescue clause and class EXCEPTION are not yet implemented.
The strip instruction is parsed but not yet implemented.
Incomplete ELKS compatibility... but we are improving it.
Command line arguments cannot be given as argument of the root procedure
(not yet implemented).
For the time being, you can use features of GENERAL.
The deep_* family is not yet implemented (deep_copy,
deep_clone, ...).
I am also teaching my students that a good class does not need deep_*
features ;-). In a good class is_equal and copy should be redefined
so that clone and equal works fine.
