Why can I not subtract 2 local variables of type nat from each other and assign that result to another local variable in a view in smartpy?
Subtractions are implicitly taken as int due to the possibility of negative results. Therefore, the variable sub is of type int here.
To resolve this, wrap sub as sp.as_nat(sub) on the dividend.

How do you set the time of a transfer when testing contracts with SmartPy?
Use now = sp.timestamp(10).
We used to allow now = 10 but this is not well typed.
(also, obviously, the exception message should be better)

How can I assign values for a map-type in an archetype test script?

How can I assign values for a map-type in an archetype test script?
The expected type reads "an array of pairs of string and bytes", and [" ", tmdBytes] is just a pair, hence I guess the following value should make ti:

Why does unpacking a record that has a key containing bounded data fail with `to_value sp.TBounded` in smartpy?
It is unsafe without a dynamic check.
We need to determine what the most natural and/or appropriate decision is (very possibly: continue forbidding it).

Why does calling sp.address() with a dynamic value inside an entrypoint fail?
That is not possible, sp.address(x) expects x to be a python string.
params.address is a michelson value of type string and michelson does not have any instruction to explicitly cast a string to an ...
