 The signed integers integers are in the range -128..127 for bytes,

+Only for ``const`` numbers, you can use larger values (32 bits signed integers). The compiler can handle those

     Doing math on signed integers can result in code that is a lot larger and slower than
     when using unsigned integers. Make sure you really need the signed numbers, otherwise

 Future Things and Ideas
 ^^^^^^^^^^^^^^^^^^^^^^^
 
+- a way to specify subroutine params for normal (non-asmsub) subs to be in r0-r15 registers instead of allocating a new localvariable for them
+- the previous should give another footgun warning (the @dirty info should be a footgun warning/info as well). Need a switch to turn off footgun warnings.
 - something to reduce the need to use fully qualified names all the time. 'with' ?  Or 'using <prefix>'?
 - on the C64: make the floating point routines @banked so that basic can be permanently banked out even if you use floats?  But this will crash when the call is done from program code at $a000+
 - Libraries: improve ability to create library files in prog8; for instance there's still stuff injected into the start of the start() routine AND there is separate setup logic going on before calling it.
