Sources can be *derived* by wrapping them in functions. A wrapped source
effectively becomes a new source.
Derived sources should be pure functions. This is where the same output is
always produced for the same input no matter how many times it is reran.

local count = source(0)

Sources on their own aren't very special, the above can be achieved with plain
variables. The real use for sources become apparent when used in combination
with Vide's *reactive scopes*. When a source is read from within a reactive
scope, it can automatically rerun the scope that reads it when the source is
updated in the future.
with *effects*. Similar to a signal and connection, a source and effect allows
you to do things like automatically updating UI when a source is updated.
