Summary0000218: Feature request: mdb commands for working with common data structures.
DescriptionOften when using the degger I'd like to know something about a data structure.

browser> print
proc_info(context("mandelbrot.m", 279),
  varset(var_supply(10),
    map([(var(1) -> "TypeInfo_for_X"), (var(2) -> "TypeInfo_for_Y"),
      (... -> ...), ...]), map([])),
  map([
    (var(1) ->
      defined_type(qualified(unqualified("private_builtin"), "type_info"), [],
        kind_star)), (var(2) -> defined_type(qualified(...), ...)),
    (var(...) -> ...), ..., ...]), [var(21), var(22), var(...), ...],
  varset(var_supply(0), map([]), map([])),
  yes([(ground(...) -> ...), ..., ...]),
  [user_defined_mode(qualified(...), ...), ..., ...], no, no, ...)
browser> cd 3
browser> print
map([
  (var(1) ->
    defined_type(qualified(unqualified("private_builtin"), "type_info"), [],
      kind_star)),
  (var(2) ->
    defined_type(qualified(unqualified("private_builtin"), "type_info"), [],
      kind_star)),
  (var(3) -> defined_type(qualified(unqualified(...), ...), [], ...)),
  (var(4) -> higher_order_type(...)), (... -> ...), ...])

What I want to know at this point is var(21) present in this map and what is it's value.

It'd be nice to have commands to work with maps, sets, lists, and perhaps other commonly-used data-structures to anwser these questions. This should be without
using the clunky compile a .m file and dynamically load it into the binary being debugged operation.

Just wanted to check if you're aware of the 'open' command. This opens a given term in your editor. I generally find this sufficient for checking whether data structures contain particular values.

That's helpful, but not perfect.

It won't open subterms for me, such as "open 5/6"

Instead I have to match parens (vim helps) and count.
