parameters (x : Nat) (y : Nat)
  add : Nat
  add = x + y
Implement new parameters syntax Previously, parameter block reused the same syntax as in Idris1: ``` parameters (v1 : t1, … , vn : tn) ``` Unfortunately this syntax presents some issues: - It does not allow to declare implicit parameters - It does not allow to specify which multiplicity to use - It is inconsistent with the syntax used for named arguments elsewhere in the language. This change fixes those three problems by borrowing the syntax for declaring type parameters in records: ``` parameters (v1 : t2) (v2 : t2) … (vn : tn) ``` It also enables other features like multiple declarations of arguments with the same type: ``` parameters (v1, v2 : Type) ``` 2021-04-19 19:48:53 +03:00			`parameters (x : Nat) (y : Nat)`
Add test script They don't all pass yet, for minor reasons. Coming shortly... Unfortunately the startup overhead for chez is really noticeable here! 2020-05-19 20:25:18 +03:00			`add : Nat`
