Endless loop of t/selftest.t

[niner]

When trying to install on current rakudo, the tests run into an endless recursion. Attaching a backtrace:

I'm not sure what changed but there are various things in exported symbols. Like JSON library that is imported...

I have similar issues ever since upgrading perl6

[teodozjan]

The problem lies in https://github.com/teodozjan/pod6-coverage/blob/master/lib/Pod/Coverage/Full.pm6#L146

for $whoO.WHO<EXPORT>.WHO<ALL>.WHO.values -> $val 

Contains all imported modules. In this case JSON and everything goes into indefinite recurstion. I can add double check protection but I'm afraid this hacky solution is wrong. JSON is not a part of tested module so should not appear here at all

> Pod::Coverage::Full.WHO<EXPORT>.WHO<ALL>.WHO.values
Method 'gist' not found for invocant of class 'NQPMatch'
> Pod::Coverage::Full.WHO<EXPORT>.WHO<ALL>.WHO.keys
(NQPMatch NQPCursorRole HLL NativeCall QRegex Grepper QAST NQPCursor NQPRegexMethod JSON NQPRegex)

on the other hand:

> use Test::Coverage
> Test::Coverage.WHO<EXPORT>.WHO<ALL>.WHO.values
(sub coverage_ok ($metafile) { #`(Sub|151560720) ... } sub subtest_anypod_ok ($metafile, $identity = { ... }) { #`(Sub|151560872) ... } sub subtest_coverage_ok ($metafile, $identity = { ... }) { #`(Sub|151561024) ... })

Perl6 is under heavy development now. Everyday I have different error so this defect has to wait until Christmas

[teodozjan]

There is no longer infinite loop
