But you simply don't need that: you can just die or warn in the usual way within your ternary operator, as you can see in the following Perl one-liners: 

$ perl -e '$die_on_err=shift; 0 or ($die_on_err? die "failed\n" : warn
+ "warning\n")' 1
failed

$ perl -e '$die_on_err=shift; 0 or ($die_on_err? die "failed\n" : warn
+ "warning\n")' 0
warning
