func ValidateCalls ¶

func ValidateCalls(exprs []core.Expr, registry *stdlib.Registry) error

ValidateCalls walks the AST and checks that every function call refers to a function that exists in the registry. This is a lightweight static check - argument types are validated at runtime

The walk also prepares nodes in place, so it must run before the program is evaluated: regex literals are compiled, timestamp literals are parsed, and constant sub-expressions are folded into core.ConstExpr (see fold.go).
