cli_bullets_raw seems to try to glue substitute <var>, is that the expected behaviour?

[sebkopf]

It seems that cli_bullets_raw tries to glue substitute <x> for the value of x, which fails because parent.frame() is not passed to glue_cmd in cli_bullets_raw. I don't understand if this is expected behaviour (the attempt to substitute) or something that is missing in cli_escape to gsub("<", "<<", ...) and gsub(">", ">>", ...). Below is a reprex.

library(cli)
x <- 5

# as expectd: styles and performs glue substitutions for {var} but not for <var>
"{.field field} {x}" |> cli_bullets()
#> field 5
"{.field field} <x>" |> cli_bullets()
#> field <x>

# as expectd: does NOT style or perform glue substitutions
"{.field field} {x}" |> cli_bullets_raw()
#> {{.field field}} {{x}}

# unexpected: seems to try to glue substitute x (but parent.frame() not passed to glue_cmd so it fails)
"{.field field} <x>" |> cli_bullets_raw()
#> Error in eval(expr, envir = envir): object 'x' not found

# solves the problem: replaces < wit << and > with >>
"{.field field} <<x>>" |> cli_bullets_raw()
#> {{.field field}} <x>
