Comment (by ChopinBach):

 Replying to [comment:2 timmydcrawford]:
 it doesn't handle something like
 >
 > {{{
 > categories=[1,2,3]
 > }}}

 I think that is expected, because that is equivalent to a string not an
 array literal in `x-www-form-urlencoded`, so it is like saying `'left
 bracket 1,2,3 right bracket'`.  If you want to pass an array via query
 params you have to do `?categories[0]=1&categories[1]=2` at least that is
 how PHP can handle array input for `x-www-form-urlencoded` requests; not
 sure if other languages do things differently. We could do something to
 make it work for `[1,2,3]`, but it would probably over complicate things,
 even though that looks better to me too.
