Having is<class> available for classes that are not yet implemented in Octave
would be useful for compatibility with Matlab. This is, for example, already
the case with isstring, even if, as commented in bug #50855
<https://savannah.gnu.org/bugs/index.php?50855#comment10>, it would be better
if the implementation was returning 'isa (s, "CLASS")' instead of 'false'.
isStringScalar is also available in the same bug report.

Other functions that could be implemented in the same way are listed below:


iscalendarduration
iscategorical
iscodistributed
isdatetime
isdistributed
isduration
isenum
isgpuarray
isreplicated
istable
istabular
istall
istimetable


Would you consider their inclusion in Octave even if the corresponding class
is not there yet?
