Ultimately all static strings should be qstr. This entry in the type structure is only used for printing error messages (to tell the type of the bad argument), and printing objects that don't supply a .print method.
Can't decide which is better for string type, char or byte pointer. Changing to char removes a few casts. Really need to do proper unicode.
