@bep do you think we could fix optional positional parameters for shortcodes in 0.39 so that they can be used alongside with/if/cond (just like named parameters) ?
I was just awaiting for confirmation that a different behaviour is expected:
If everybody agrees positional params should return an empty value too (so that they can be chained with with or if to check for their existence), I will be glad to make a PR to fix this. @bep, what do you think?
Either this or I can document the current behaviour, whichever you think is more appropriate
