Python TSG: Unable to parse lambda in parameter/arguments

[SubhamPramanik]

Python Code:

for tag in soup.find_all(href=lambda x: x and x.startswith("data:")):

on_backoff=lambda details: print(

update_available = check_version(lambda msg: None)

ranked_definitions = sorted(ranked_definitions.items(), reverse=True, key=lambda x: x[1])

directories.sort(key=lambda dname: pass_counts[dname], reverse=True)

Failing Stanza:

(parameter/identifier) @param @name
{
  attr (@name.def) node_definition = @name
  attr (@param.param_name) push_node = @param
  edge @name.def -> @param.param_name
  edge @name.def -> @param.param_index
  edge @param.input -> @name.def
}

A more minimalistic example

Input

sorted([1, 2, 3], key=lambda x: x)

CST

(module [0, 0] - [1, 0]
  (expression_statement [0, 0] - [0, 34]
    (call [0, 0] - [0, 34]
      function: (identifier [0, 0] - [0, 6])
      arguments: (argument_list [0, 6] - [0, 34]
        (list [0, 7] - [0, 16]
          (integer [0, 8] - [0, 9])
          (integer [0, 11] - [0, 12])
          (integer [0, 14] - [0, 15]))
        (keyword_argument [0, 18] - [0, 33]
          name: (identifier [0, 18] - [0, 21])
          value: (lambda [0, 22] - [0, 33]
            parameters: (lambda_parameters [0, 29] - [0, 30]
              (identifier [0, 29] - [0, 30]))
            body: (identifier [0, 32] - [0, 33])))))))

Suggested fix

++[
  (parameters
    (_) @param) @params
++  (lambda_parameters
++    (_) @param) @params
-- {
++] {
  node @param.param_index
  node @param.param_name

  attr (@param.param_index) push_symbol = (named-child-index @param)
  edge @param.param_index -> @params.before_scope
  edge @params.after_scope -> @param.input
  edge @param.param_name -> @params.before_scope
}

Thanks for reporting these and other issues! If it's possible to create PRs for issues where you have suggested fixes, that will make it easier for me to get them in with the limited time I currently have for this project.
