Not sure why AUTOLOAD is needed in CGI anyway, the allowed HTML-tags seem to be exported from CGI to the local namespace, but only spring into existence within the stash of %CGI:: after first use! ¹

Speed can't be that relevant, CGI doesn't do any syntax validation, so the same generic function could be installed at import time for all html-tags, maybe with a closed over $tag_name if necessary.

What am I missing?

¹) didn't know it's possible to predeclare an AUTOLOADed sub ... (scratch)

update

interesting... 

  DB<181> package Test; sub AUTOLOAD { $AUTOLOAD,\@_ }

  DB<182> bar(1,2,3)
Undefined subroutine &main::bar called at (eval 196)[multi_perl5db.pl:
+644] line 2.

  DB<183> Test::bar(1,2,3)
 => ("Test::bar", [1, 2, 3])

  DB<184> *bar=\&Test::bar
 
  DB<185> bar(1,2,3)
 => ("Test::bar", [1, 2, 3])

but

  DB<186> *foo=*Test::foo
 
  DB<187> foo(1,2,3)
Undefined subroutine &Test::foo called at (eval 206)[multi_perl5db.pl:
