Subject: Replace the su_handler[] dispatch table by a switch
X-Git-Tag: rt104751~4
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FScope-Upper.git;a=commitdiff_plain;h=0fb65259707f0db2eda122e573c417865fc91435

Replace the su_handler[] dispatch table by a switch

This lets us inline the handlers in su_pop(), which is somewhat clearer.
