[REBOL] Did you know? - 'Bind is stackable!

Did you know? - 'Bind is stackable!
I didn't - until I tried it. Have a look at the line:
if all bind bind Filter 'File 'Header
Unit: function ['Name [word!] Base-Directory [file!] Sub-Directory [file!]
Filter [block!]] [Script Header] [
error? try [
if system/script/parent/header/File = %user.r [
set Name make object! [
Directory: file!
Files: block!
]
change-dir Base-Directory
Name: get Name
Name/Directory: Sub-Directory
Name/Files: read Name/Directory
change-dir Name/Directory
foreach File Name/Files [
Script: load/header File
Header: first Script
if all bind bind Filter 'File 'Header [
do Script
]
]
Name/Directory: join Base-Directory Sub-Directory
]
]
]
Unit Patches %/C/Rebol/Patch/ %Patches/ [
Header/File = File
Header/Patch = Header/Name
]
Unit Enhancements %/C/Rebol/Enhancement/ %Enhancements/ [
Header/File = File
Header/Enhancement = Header/Name
]
BTW, 'Unit is my keystone building block for Patches, Enhancements for Rebol
and Components and Plug-ins for Rebol applications, like RebMail.
Note that the order of 'File and 'Header didn't matter. Which leads me to
wonder if an enhanced version of 'bind that allows a block would be of
interest to people or Rebol crew.
