Safe optimizations. Mir uses unsafe ugly workarounds somehow in 
some places and doesn't improve some stuff that can be improved. 
Lazy tensors are used in

https://github.com/typohnebild/numpy-vs-mir

which has few kernels. The fastest one is `ndslice`, which uses 
lazy zipped tensors. Comparing with Phobos zipped ranges, Mir's 
zipped tensors are mutable.
