There's a newish function in git, not yet documented. I'd appreciate
any comments as to whether it's worth keeping.
The mkarray() function creates an array of a specified type in
extenso, that is, by specification of a number of elements (as many as
you like). Examples:
strings S = mkarray("1 A", "2 B", "3 C", "4 D")
matrices M = mkarray(I(3), zeros(n,1), qform(x,A))
