say $pCOMMAND.parse('DateTime');

# ｢DateTime｣
#  metadata-entity-command => ｢DateTime｣
#   entity-metadata-name => ｢DateTime｣
#    0 => ｢DateTime｣
#     word-value => ｢DateTime｣

say $pCOMMAND.parse('time series');

# ｢time series｣
#  data-type-entity-command => ｢time series｣
#   entity-data-type-name => ｢time series｣
#    0 => ｢time series｣
#     word-value => ｢time｣
#     word-value => ｢series｣

say $pCOMMAND.parse('Titanic');

# ｢Titanic｣
