I think i understand what this is about.

Stjepan would like to have the tempo value used both in header as well
as in actual tempo definition.  It is possible to define a variable
and use it in the header:

trololo = 123

\header {
  title = #(string-append
            "bang! "
            (number->string trololo)
            " foobars in a bottle")
}

The problem is, as David already noticed, that a variable cannot be
used in \tempo command:

{
  % this crashes:
  \tempo 4 = \trololo
  c'
}

Stjepan, is this what you mean?
