How come petsc4py has the (nonstandard?) v.setAttr('name',value) and v.getAttr('name') instead of <a href="http://v.name" rel="noreferrer" target="_blank">v.name</a> notation? Could they be refactored to have "normal" attribute behavior? If not, could a v.hasAttr('name') be added? <br>
<br>
Similarly, how come numpy arrays seem to have no way to set attributes on them? <br>
<br>
PyTorch tensors seem to support the standard <a href="http://t.name" rel="noreferrer" target="_blank">t.name</a> handling of attributes.<br>
