Perl Security: 5. When using functions, remember...
Why do we have to bother with @_ ?

Most languages behave differently when declaring functions

In C: int myfunc (int var1, char* var2);

In Python: def myfunc (var1, var2);

In PHP: function myfunc ($var1, $var2) { (...) }

and so on.

Why in Perl we have to fiddle around with @_, $_[x], shift, etc?

Think back on the early Perl versions...

No namespaces

No lexical variables

@_ means no namespace exhaustion

@_ is (was?) an ellegant solution
