Hi everybody, so I have some doubts about Teal:
I have to use Smart Contracts, so code in TEAL, to implement some algorithms that use constructs belonging to more expressive languages (e.g. loop cycle), such as Python.
So, my question: which are the limits of language?

One example is that branching is limited; you can’t go _back_ in the code (to a previous instruction), TEAL moves only forward. However, you can skip parts of the code depending on a condition.
So you can’t loop. However, creating contracts is very cheap. So you should try to do as much computation as you can beforehand (like collecting participants of a shared fund), and then put them into the contract concretely.
