-// A$$anonfun$bob1$1.class

-// A$$anonfun$bob1$3.class

-// % ls -1 /tmp/trunk
-// A.class
-//
-// Observations:
-//
-// (1) The inlined version accesses the field: the explicit one calls the accessor.
-// (2) The inlined version fails to eliminate boxing. With reference types it emits
-// an unneeded checkcast.
-// (3) The private var debug is mangled to A$$debug, but after inlining it is never accessed
-// from outside of the class and doesn't need mangling.
-// (4) We could forego emitting bytecode for ifelse entirely if it has been
-// inlined at all sites.
-//
-// Generated bytecode for the above:
-//
-// public final int bob1();
-// Code:
-// Stack=1, Locals=1, Args_size=1
-// 0: aload_0
-// 1: getfield #11; //Field A$$debug:Z
-// 4: ifeq 14

-// 21: ireturn

-// Stack=1, Locals=1, Args_size=1
