Yep, accounted for, KDE::versionString() returns const char *, but that was
solvable with a cast.
Just to be clear, in all situations it's compiling cleanly, it's just not
resolving the method when a heredoc isn't used.

Essentially, yes.

I'll check for this, but again, it's compiling.

versionString() is in the KDE namespace. It's no different than trying to call
a perl subroutine that exists in package KDE from main without qualifying the
package.
I could certainly attempt some trickery to reassign it to std, but like I
said, it compiles everytime and runs cleanly and as expected when it's in a
heredoc.

Correct.

Very much so. Technically I have a working product at this point, however I'd
really prefer to not use a heredoc. I imagine it's something very subtle
(e.g., I snipped the POD in the document but there is an __END__ in there,
maybe that's confusing Inline). I've got some other matters to attend to
today and will give it a solid try in a few hours.
I'll scour your examples and see if I have anything different that I may have
overlooked.
Thanks again for your help.
