which is nothing at all like the [lremove] proposed in this TIP!

Removal by value ("value equals X") appears to be what previous
implementations of [lremove] do already.

list.remove removes a single element, which is already handled, errr,
handily by [lreplace].

[lreplace]. 

> set list [lreplace $list [lsearch $list "item"] [lsearch $list "item"]

So I take it you would prefer a different [lremove] TIP that performs
the [lsearch] internally, rather than this TIP that uses indices.
