in reply to include statement in perl?

Update Corrected @ARGV to *ARGV to correct the error noted by Aristotle++ below. 

use strict;
use warnings;
use CGI;
....
print do{ local (*ARGV,$/), @ARGV='files/my.html'; <> }; # Hic!
....

Re^2: include statement in perl? (idiom with caveats)

    Just be careful that the ARGV filehandle is not currently open on another file, otherwise it won't quite do what you expected.

    Update: localizing the entire *ARGV glob works, but doesn't work in less than recent Perls - it breaks on less than 5.8, IIRC 5.6 - see (tye)Re: Cheap idioms.
