Code:
obj
    Hud
        Unlockable
            Learn_Techniques
                icon_state = "learn tech"
                Click()
                    var/learn = input("Do you want to learn all the techniques?\n- This is just temporary until all techniques are done","Learn Techniques") in list("Yes","No")
                    if(learn == "No") return
                    else
                        usr.techniques = initial(usr.techniques)
                        var/list/techs = typesof(/obj/Technique/)
                        techs -= /obj/Technique/
                        for(var/obj/Technique/T in techs)
                            var/A = new T
                            usr.techniques += A
                    ..()


Problem description: Well, for testing purpose I want it so you can learn every technique defined as obj/Technique, but I keep getting runtime errors such as "usr.techniques += Fly; invalid" and i've tried alternate ways but it seems it just ends up clearing the techniques list.

YOU'RE DOING IT WRONG!
for(var/O in typesof(/obj/Technique/) - /obj/Technique/) 
    if(!(locate(O) in usr.techniques))
        new O(usr.techniques)

YOU'RE DOING IT WRONG!

Presumably, techniques is a list, not an atom. Therefore, supplying it as an argument to new() for the loc parameter won't work, because an atom's loc can't be a list. You'd have to do:

techniques += new O()

Since when can't a list be a location? o.0
I WAS NOT INFORMED OF THIS!

I've never had a problem with adding objects to a list before though.

usr.techniques = newlist(arglist(typesof(/obj/Technique)-/obj/Technique))

You can add objects to a list all you want. However, their loc won't be that list, and as the first argument to new() is the loc of the object to be created, you can't add an object to a list by using that argument to new().

You know, I was screwing around with something like this a while ago and I totally forgot about the arglist() proc. Though, it still doesn't work at compile-time so you can't use it in the manner I was trying to.

Your little tidbit helped, and the problem has been resolved, I thank everyone for helping me.
