If joined colonpairs are after a position arg, only the first colonpair gets registered​:

  <Zoffix__> m​: -> *@​_, *%_ { dd [@​_, %_] }("/", :r​:w​:d​:x)
  <camelia> rakudo-moar 1b9d53​: OUTPUT​: «[["/"], {​:r}]␤»

But if they're first in line, then all do​:

  <Zoffix__> m​: -> *@​_, *%_ { dd [@​_, %_] }(​:r​:w​:d​:x, "/")
  <camelia> rakudo-moar 1b9d53​: OUTPUT​: «[["/"], {​:d, :r, :w, :x}]␤»

When in a [], only first one is obtained as well​:
  <Zoffix__> m​: dd [​:r​:w​:d​:x]
  <camelia> rakudo-moar 1b9d53​: OUTPUT​: «[​:r]␤»

And when in a {}, all are obtained, but only the first one gets value True (related?)
  <Zoffix__> m​: dd {​:r​:w​:d​:x}
  <camelia> rakudo-moar 1b9d53​: OUTPUT​: «Hash % = {​:d(1), :r, :w(1), :x(1)}␤»

I wonder, is it a dup of RT #​124553 and RT #​125353 ?

The RT System itself - Status changed from 'new' to 'open'

The examples given by Zoffix above seems to have been fixed by rakudo/rakudo@9135914
