No I don't try to get the sub-argument, but the type of the subargument. But I'm not sure I can get it. > (isTimes ((argument ((kernels resFloat).1)).1)).1::Float > (isTimes ((argument ((kernels resInteger).1)).1)).1::Integer > argument ((kernels resComplex).1).1::Complex Integer Imagine I know that a is an Expression... My function don't know if a is an Expression Float, or an Expression Integer... I want to do as below in an *.input file. Myfunction (a : Expression ...) : String == is a an Expression Integer => "Integer" -- or an other calculus. is a an Expression Franction Integer => "Rationnal" is a an Expression Complex ... => "Complex" -- so I can use real and imag. is a an Expression Float => "Float" "A rare domain".
