lrepeat was defined in TIP 136 [L1 ] , which has been approved for incorporation into Tcl 8.5.0 .
Eventually, the doc will be here: http://www.tcl.tk/man/tcl8.5/TclCmd/lrepeat.htm
lrepeat number element1 ?element2 element3 ...?
This command builds up a list by repeating elements. It will be a part of Tcl 8.5.0 . Note that Tcl 8.5 is available in an early developer form from ftp://ftp.tcl.tk/pub/tcl/nightly-cvs/tcl-*gz . Early access to Tk 8.5 is there as well.
An example of how it will work is
lrepeat 3 a => a a a
lrepeat 3 [lrepeat 3 0] => {0 0 0} {0 0 0} {0 0 0}RS: Note the possible confusion with string repeat's syntax:
% string repeat a 5 aaaaa
FW: A forward-compatible version for versions before 8.5 is available in Additional list functions
