Algorithm name could define result length.
Yes, for constants.
We need to decide whether the algorithm name can be passed dynamically
(and thus be presented as "value" in the grammar) or must be predefined
(via a string literal or maybe token). The latter gives us more
flexibility regarding the result type. Tricks with runtime type coercion
are possible but require careful programming at the user side (proper
CASTs must present), I'd rather avoid that.
