Module function 

Function-name classification for plan analysis.

Identifies functions whose arguments are evaluated per element of a list (lambda-style evaluation). Plan passes that reason about evaluation order (for example factorization flattening) consult this module instead of hardcoding function names, so the classification stays consistent wherever it is used.

Functions

is_list_lambda

Report whether a function evaluates an argument per list element.

list_lambda_arg_index

Argument position of the per-element expression for a list lambda.
