Deeper investigation lead me to the conclusion that expressions like
<workitem>.attributes[key]
and
<workitem>.attributes[key] = value
and
<workitem>.attributes.delete key
should disappear from to project(well, not from where the functions are
defined :) ), being substituted in the same order
<workitem>.lookup_attribute key
and
<workitem>.set_attribute key, value
and
<workitem>.unset_attribute key
Wdyt?
