Actually, both the implication of permanent attachment and spatial rather than temporal seem to fit. The first is clear cut--it is a permanent modification, unlike some of the other modules that support unwrapping.

The second is more of how you think about it. I think about it as a code block that's inserted at the very beginning, i.e. "as a string", so

prepend foo => sub { # Remove the invocant. shift; }; sub foo { print shift; }
is equivalent to
sub foo { { # Remove the invocant. shift; } print shift; }
That doesn't mean I'm set on prepend. Spelled-out suggestions are still welcome.
