Indeed. MYMETA.yml is the authoritative source of any dependency
information and other meta info. Its inception was after I last touched
the PAR::Dist code and I don't think anybody else has since.
The problem with MYMETA is ordinarily that it's not available before
building, so most tools can't rely on it. This is different for the part
of PAR::Dist that you care about as it comes in only after build time.
Either way, we may have to eventually add META.json support to
PAR::Dist. The modules currently does many nasty things in order not to
require a YAML parser in order to work out of the box on old perls.
Repeating that for JSON would be horrible. When I spent a bit of time to
think about it, I couldn't come up with a very good solution. If it's
the case that the recent toolchain will always generate MYMETA.yml even
if there was a META.json, then we just bought some time.
I'll upload a patched PAR::Dist 0.48 within the hour.
Best regards,
Steffen
