I think this will cause problems as I myself usually want to modify the
contents after a reshape. Why not in this case have a.reshape(...) return a
view when possible and raise an error otherwise, and have the functional
form make a copy. Reshape the method then provides a path to efficient
computing, while reshape the function promotes safe computing. I like to
write classes in C++ where I can do things like
b.mul(c).add(d).div(e) all inplace for efficiency and the current situation
strikes me as similar.
