That sounds like you're in favor of dropping the module @alerque ?

[alerque]

Ha, maybe. I guess it depends a little bit on what the alternatives are. One reason I was strongly in favor of dropping the XML module is there were so much better options available in the Lua ecosystem, hence I didn't think it was worth any effort to fix or develop. If there are not solid upgrades for anybody that might be using pl.url module now I would not want to see it dropped until there was something at least as good or better that was easy to migrate too and proven to be robust across different platforms.

I guess the point of dropping that link was just to point out that in spite of being a "small" feature it is not that easy to get right. That goes for whether we work on improving the module or supporting an alternative.

Do we have any internal dependencies on pl.url?

a quick search did not show any dependencies. I was thinking of maybe copying an existing implementation and enable it for more flexible use, like luasocket one.
