[fasmg] [feature-request] __file__ as a list

Ohai,
__file__ currently holds the name of the file, that is compiled. It would be nice, if this is the list of files from the main-file to the file, which actually used __file__, e.g.
main:

Code:

include 'file1'
include 'file3'
foo

file1:

Code:

include 'file2'
macro foo
  bar
end macro

file2:

Code:

macro bar
  fail 'just fail'
end macro

file3:

Code:

macro fail message&
  irpv item, __file__
    display '->', __file__    ;the last value of __file__ would be 'file3', but thats ok
    restore __file__
  end irpv
  display '->', message, 10
end macro

IMHO custom errors are nice, but it is sometimes a bit hard to find the actual cause, when I use a lot of macros. sometimes, I do not even know where I defined the macro.
A Plus would be, if I can just restore __line__ to get the line number in this file:

Code:

macro fail message&
  irpv item, __file__
    display '->', __file__, ':'
    displayDecimal __line__   ;displays the line number as decimal value
    restore __line__
    restore __file__
  end irpv
  display '->', message, 10
  ;in this case:
  ;->main:3->file1:3->file2:2->file3:2->just fail
end macro
