Also interesting is how the variable doesn't need to be declared, since it is automatically considered a package variable.

>perl -Mstrict -e "@1

>perl -Mstrict -e "my @1
an't use global @1 in "my" at -e line 1, near "my @1"
Execution of -e aborted due to compilation errors.

Update: Ah, other special-like variables are like that too.

>perl -Mstrict -e "%!

>perl -Mstrict -e "my %!
Can't use global %! in "my" at -e line 1, near "my %!"
Execution of -e aborted due to compilation errors.
