This is what the wrapper is currently doing. But note that the
"depth" of the call to bootstrap() is different. In particular, any
special processing which "pseudo-unwinds" to upper frames (such as
error reporting by Carp) would see a "wrong" frame.
Apparently, undocumented magic of Carp hides this issue (I could not
solicit "wrong" messages with the above construct), but if goto would
work, it would be a bullet-proof way to do things.
