Existing CAS commands --> Prime discussion

Another alternative way is: eval(seq(a,1))

but the important thing is to have a functional command, makevector(), dedicated for that purpose.
For example QR() returns a sequence Q,R, with makevector() returns a vector

makevector(QR([[1,2],[3,4]]))

There is also a need to document the lowercase qr() function command
makevector(qr([[1,2],[3,4]]))
