technically yes but, nope ! it’a special kind of list just like dictionnary. Typeroute~ is practical for creating abstractions and using single inlets right. so haing a list go in the same inlet as a matrix , how do you separate them. Of as you can guess there is always a work around , even 3-4 options but I thought it would simplify things to have the option , signal bang int float symbol list matrix dictionnary.
