No, this won’t work because {{…}} is only for simple variable
interpolation; it does not support anything with a space in it.  That’s
on purpose to avoid conflicts with the embedded language syntax.

You will need to define a local variable first and reference that:

--8<---------------cut here---------------start------------->8---
process foo
  inputs
    . "something"
    . samples: "a" "b" "c"
  procedure
    define my-selection
      pick second samples: inputs
    # { echo {{my-selection}} }
--8<---------------cut here---------------end--------------->8---
