No, inlining is enabled by default. Currently only DMH invokes are
inlined, but I'm working on inlining the rest. Are you missing specific
calls?
I wanted to write a status update anyway... Yesterday I could inline
for the first time a whole GuardWithTest calling sequence (with
adjusting some switches). The inlined sequence looks like this (methods
take one int argument and return an int):
