The error is made when the programmer assumes method declarations without a 
signature mean any arguments are valid and not a (). This would be common with 
Perl 5 programmers, I can imagine.

Moreover, whe error that is shown when a call to such a method is made says it 
received 1 more argument than what the user provided, and it's not obvious that 
the one extra is the invocant.

In constrast, doing the same thing with plain subroutines shows a much clearer 
and more informative error message.
