Yeah I know :D

Right

'Same' is 'is' in a different guise and is what I object to.

A python programmer who needs/wants to think of same/is in this sense
should probably be using C or assembly

In the exceptional circumstances when 'low-level-machine-equivalence-relation'
is desired, a name carrying some of those connotations would be ok
