Dear R-devel,

When a character vector is used to subscript a list and when some of the subscripts are not present in the list names R  returns NULL for those subscripts and generate NA names for each of them:

> list(b=1)[c('a','b')]
$<NA>  <<-- generated name
NULL
$b
[1] 1


Wouldn't it be more intuitive to use the subscript name rather than to generate an NA? Something like this (not real result):
> list(b=1)[c('a','b')]
$a        <<-- more intuitive name
NULL
$b
[1] 1
