Performance: prefer lset over lreplace for modifying list values. When a list element is modified, lset does it "in place", modifying the variable itself, while lreplace works with values and returns a second copy of the list with the modified elements, creating some unnecessary overhead. On my local tests, this particular operation was around 30% faster. More details: http://wiki.tcl.tk/1485 and http://wiki.tcl.tk/2556Show less
