Note that the fat comma doesn't work here under use strict (i.e., you'd still need to quote the module name):

#!/usr/bin/perl
use strict;
use if ( 1 ) , Time::HiRes => qw(time) ;

$ ./903506.pl
Bareword "Time::HiRes" not allowed while "strict subs" in use at ./903

That’s easily fixed. The fat‐comma isn’t the only way to please use strict, you know. Just use “package-quoting” on the module name: Time::HiRes::. Now that doesn’t even need fat‐comma any longer:

% perl -Mstrict -e'printf "%s is %d chars long.\n",
                        English::, length(English::)'
English is 7 chars long.

See how that works? Perfectly use strict–complaisant, too. Nifty, eh? That means that this compiles and runs just fine:

#!/usr/bin/perl
use strict;
use if ($^V gt v5.7.3), Time::HiRes::, qw(time);

And so does this:

#!/usr/bin/perl
use strict;
use if $^V >= v5.7.3 => Time::HiRes:: => time => ();

Although some of that there just might maybe get you a tad talked about.   😻
