Accessing scope from macro unclear

[machinekoder]

Is it possible to access the caller scope of macro? I would like to do something like this:

.macro foo (bar)
.  for field  <-- iterates over outgoing.field at first call
.    foo(name)
.  endfor
.endmacro

.for outgoing
.  foo(name)
.endfor

Got it:

.macro foo (scp, bar)
.  for my.scp.field
.    foo(field, name)
.  endfor
.endmacro

.for outgoing
.  foo(outgoing, name)
.endfor
