It would be nice to have a strict feature to catch such special variable "zombies", but I'm not sure how to implement it.

Point is that $@ is a special global package variable, with the glob *main::@ , hence this glob has slots for an array, hash, function,... without being declared.

like

D:\Users\lanx>perl -E "use strict; say @@"


D:\Users\lanx>perl -E "use strict; say *@"
*main::@

IMHO in at least 95% of the cases these slots are used accidentally.

Some use them intentionally, but could activate a pragma in these cases. °
