code example error, add file name

[sztanyi]

The problem

Following example seems incorrect
`With file.dat present, this will work this way:

$ perl6 frobnicate.p6
24
file.dat
Verbosity off
Or this way with --verbose:

$ perl6 frobnicate.p6 --verbose
24
file.dat
Verbosity on`

Solution provided

Add file.dat to command line argument
`$ perl6 frobnicate.p6 file.dat
24
file.dat
Verbosity off
Or this way with --verbose:

$ perl6 frobnicate.p6 --verbose file.dat
24
file.dat
Verbosity on`

Theoretically, .file.dat should be a default value. If it does not work that way, the problem is not with the argument, but with the program itself.
