With the exception of [lsort], the other l* commands are simpler, yes.

If it would help, I'd start an ensemble version of lsearch, call it
[search] or [find] and combine it with [string
first|index|last|match|*], [regexp], [info procs|exists], [glob] and two
or three others :D

Maybe we should add a disclaimer on the slogan 'Everything is a command*)'

*) 'Yes, everything is a command, but some commands have an awful lot of
switches'

Seriously, though, I don't think it is too bad. Except that it really
does not feel very tcl-ish.

It is rather short on verbose examples, yes. I'll see what I can do.

The current binary search code uses 'leftmost' with the implied
'rightmost'. I could live with those. And -first and -last are not
claimed either.

You mean the default, no options [lsearch]?
