This is good news. Thanks!

Caution is still needed for library functions that sometimes pass arguments
by simply leaving them on stack. As this makes code faster and simpler I
consider this as a feature and not a bug, however.


A big feature wish for slang would be a support for optional arguments in a
form like

define foo(arg1, arg2=default, arg3=default2)

which would make my modes several lines shorter and much nicer.
