--- Comment #18 from Marcel de Rooy <m.de.rooy at rijksmuseum.nl> ---
If you compile (perl -cw) a script or module now that contains a use
C4::Context, you have the following warnings:

Name "Tie::Hash::FIELDS" used only once: possible typo at
/usr/share/perl/5.22/fields.pm line 135.
Name "Cache::RemovalStrategy::LRU::FIELDS" used only once: possible typo at
/usr/share/perl/5.22/fields.pm line 135.
Name "Cache::RemovalStrategy::FIELDS" used only once: possible typo 
at /usr/share/perl/5.22/fields.pm line 135.

[ PS koha-qa does the same. ]

Are these warnings somehow related to perl's Cache module containing things
like below?

use base qw(Tie::Hash);

my $strategy = $args->{removal_strategy} || 'Cache::RemovalStrategy::LRU';
