the arg is required with lrepeat.

list(3tcl) Tcl Built-In Commands list(3tcl)__________________________________________________________________________________________________________________________________________________NAME
list - Create a list
SYNOPSIS
list ?arg arg ...?
_________________________________________________________________DESCRIPTION
This command returns a list comprised of all the args, or an empty string if no args are specified. Braces and backslashes get added as
necessary, so that the lindex command may be used on the result to re-extract the original arguments, and also so that eval may be used to
execute the resulting list, with arg1 comprising the command's name and the other args comprising its arguments. List produces slightly
different results than concat: concat removes one level of grouping before forming the list, while list works directly from the original
arguments.
EXAMPLE
The command
list a b "c d e " " f {g h}"
will return
a b {c d e } { f {g h}}
while concat with the same arguments will return
a b c d e f {g h}
