Hello Justin,
"What is the difference between a (constant/immutable) value and the
result of calling a side-effect free function that returns the same?"
A const value can't be changed from the current context but could be changed
via another alias or inside a non side effect free function or via one of
those in another thread.
An immutable value can't change, end of story.
The value a side-effect free function returns can change as soon as anything
changes, a local var (via nested functions) global var or anything addressable
through them.
The function most closely resembles the const var.
