I am posting this for Dan Book, who is having trouble getting email to 
perlbug through.

The build options and version of perl is immaterial here, except since 5.22.

When the warning "Scalar value @arrayname[0] better written as 
is triggered (any time an array slice is used with only one element), 
this results
in an error if the array's name starts with 'inf'. Code to reproduce:

use warnings;
my @infasdf;
my @x = @infasdf[0];

Error from above code (since 5.22): Cannot printf Inf with 'c' at (IRC) 
line 3.
