IFTE odd behaviour

That seems reasonable, with perhaps one exception. The TrueClause and the FalseClause can also be lists:

IFTE({1,0,1,0,0},{2,4,6,8,10},{1,3,5,7,9}) --> {2,3,6,7,9}

but the lists of course have to all be the same size:

IFTE({1,0,1,0,0},{2,4},{1,3,5}) --> Error: Invalid input

So I'd think the following ought to give the same "Invalid input" error:

IFTE({},{2,4,6},{1,3,5})

since the lists' sizes are not consistent.
