2.14.2-syntax for listed Staffs in SimultaneousMusic?

[Thomas Morley]

Hi all,

currently I'm doing some research through the lily-versions.
Therefore it would be great I could have a test-case working even for 2.14.2

The following works back to 2.16.2
How would be 2.14.2-syntax?
Any hint, even for more clumsy coding, appreciated. I need that
mapping over different staff-spaces.

<<
  $@(map
     (lambda (n)
       #{
     \new Staff \with { \override StaffSymbol #'staff-space = $n }
       { c''1 }
       #})
     (iota 12 0.25 0.25))

Cheers,
  Harm
