Lexical vs Dynamic Scope Makes No Difference in Functional Programing
- For Advanced Coders, Lexical vs Dynamic Scope. Extra Tip.
- If you write your code in a pure functional programing style,
- Lexical vs Dynamic Scope makes no difference.
- They become an issue when you use global variables, and a local one has the same name.
- In other words, if all your variables have unique names, it doesn't matter neither.
- This is so for any programing language, python JavaScript lisp cpp rust haskell etc.
- The Lexical vs Dynamic Scope always excites the c cpp etc types of bitdiddlers.
- precisely because they thrive on tricks of variable binding, memory states, and no like functional programing.
Lexical vs Dynamic Scope in a Term Rewriting System
- For Advanced Coders, Computer Science. Lexical vs Dynamic Scope.
- Complicated issue, but more so, they take different meaning in a term rewriting system such as Wolfram language.
- Because in a term rewriting system, every symbol is global.
- If you want local variable with lexical scope, what it really means, is change the symbol names in a block.
