For what it is worth, the Sage Notebook and Sage Cell work that way
because at the time (2006) that we implemented the first version, we
couldn't figure out how to get it to work the way Jole wants. And
that weird design just sort of stuck.
In SageMathCloud, doing
integrate(1,x)
integrate(2,x)
outputs
x
2*x
It does this properly by breaking the input into blocks, and exec'ing
each block separately. I think SageCell (and IPython Notebook,
etc.) should do the same, but nobody listens to me when I suggest
this.
