I don't know whether I support the proposal or not, but in reading Mark Russel's email, I realized that I just recently ran into a use case:

[snip example where 3 lines are duplicated twice, and a 2 line subset are duplicated in a third location]

using something like currsuffix := or Phillip J. Eby's suggestion of .currsuffix = would allow this code to be factored out into a function.

In this particular example, there is no net reduction in line use. The execution speed of your algorithm would be reduced due to function calling overhead. There may be a minor clarification improvement, but arguably no better than the Richie Hindle's functional goto implementation for Python 2.3 and later.
