TL;DR

Given: sequence of Token and Grammar
Where:
   Token := tuple[name:string, value:string, parent:Token]
   Grammar := Table[system.string, proc(x:Token):string]
Return: string of token values passed through the grammar

When implementing my translator, I came to the conclusion that I need to perform some action depending on the token, I understand that it would be more correct to implement this functionality using conditional branching, but I am interested in a different approach, in which, having received the name of the token, I do some interaction with it.

The easiest way to implement this is Table[system.string, proc(x:Token):string]

However, I am not satisfied with the fact that I cannot generate it during compilation. Or I can, but I don’t know how.

Since I have a little experience with php, from which I know that I can work with *strings as functions *

    function a(int $a){ 
        return $a + 3;
    }
    echo "a"(1); // 4

Based on this, is there a way in Nim that would allow declaring a set of functions in advance to access them in this way?
