+ * Normally, during compile time, PL_curcop == &PL_compiling is true. However,
+ * Devel::Declare makes the interpreter call back to perl during compile time,
+ * which temporarily enters runtime. Then perl space calls various functions
+ * from this file, which are designed to work during compile time. They all
+ * happen to operate on PL_curcop, not PL_compiling. That doesn't make a
+ * difference in the core, but it does for Devel::Declare, which operates at
+ * runtime, but still wants to mangle the things that are about to be compiled.
+ * That's why we define our own PL_curcop and make it point to PL_compiling
+ * here.
