#15 Yard: sneaky unitialized value

[Jonathan Rosenbaum]

Despite my best attempts this bug remains:

Use of uninitialized value in concatenation (.) at Yard.pm line 233, <CONTENTS> line 60.

The line in CONTENTS being referred to is a known line referring to a
non-existent file. In this case that file that is being tested is
"/dev/pilot".

The test used on the file:

if (-l $file and readlink($file) =~ m|^/proc/|)

But the error can't be reproduced. The error doesn't cause any ill effect
to the underlying function, but it is annoying.
