What is the difference between Numpy's array() and asarray() functions?

Why are functions in Ocaml/F# not recursive by default?
...ited this syntax from OCaml.
For example, superceding the function p when computing the Shannon entropy of a sequence in OCaml:

-. fold p 0.0
Note how the argument p to the higher-order shannon function is...
