R devel - Aug 2022 - get() promise to missing arg

Hi,

Please consider the following:
> e <- new.env()
> delayedAssign("p", quote(expr = ), assign.env = e)
> e$m <- quote(expr = )
> identical(e$m, e$p)
[1] TRUE
> 
> get("p", e)
> get("m", e)
Error in get("m", e) : argument "m" is missing, with no
default

Although objects m and p are identical(), get() behaves differently for them (in
R version 4.2.1). Is this intended?

I stumbled across this in the context of utils:::print.ls_str(), which fails
when encountering a promise to the missing arg:
> ls.str(e)
m : <missing>
p : Error in inherits(o, "error") : argument "o" is missing,
with no default

Best,
Andreas
