+/* OP_ENTERSUB and OP_RV2CV flags
+
+Flags are set on entersub and rv2cv in three phases:
+  parser  - the parser passes the flag to the op constructor
+  check   - the check routine called by the op constructor sets the flag
+  context - application of scalar/ref/lvalue context applies the flag
+
+In the third stage, an entersub op might turn into an rv2cv op (undef &foo,
+\&foo, lock &foo, exists &foo, defined &foo).  The two places where that
+happens (op_lvalue_flags and doref in op.c) need to make sure the flags do
+not conflict.  Flags applied in the context phase are only set when there
+is no conversion of op type.
