Description
Follow up to this comment: https://github.com/rstudio/positron/pull/559#discussion_r1195182114
> rcd <- new_rcrd(list(x = 1:10, y = letters[1:10]), class = "mylist")
> length(rcd)
[1] 10
This creates a record of size 10 with 2 fields. But the environment pane only shows the record as a boring list:
even if it has a format() method:
> format.mylist <- function(x, ...) paste("(", field(x, "x"), ", ", field(x, "y"), ")", sep = "")
> rcd <- new_rcrd(list(x = 1:10, y = letters[1:10]), class = "mylist")
> rcd
<mylist[10]>
[1] (1, a) (2, b) (3, c) (4, d) (5, e) (6, f) (7, g) (8, h) (9, i)
[10] (10, j)
Should it look more like format(rcd):
fmt <- format(rcd)

Research direction
Start with the environment pane's handling of R objects and the discussion linked from posit-dev/positron#559. Reproduce the vctrs::new_rcrd example from the issue and compare the pane's display with format(rcd). Done means the record is presented using its formatted representation instead of as a generic list.
