I'm not sure I understand "hold the tool up to the data".  If you mean the
data is persistent, and the tools operate on the persistent data, then

Here is something I wrote today:
Passing an object as an argument to a function doesn't invoke a explicit
transfer of data; it connects an instance of the function to a history of
information flow-- i.e. other functions.  An object, then, is a
placeholder, a state.  The information contained by the object marks where
the object is in a path of dependencies (a state machine)?

All data is metaprogramming information.  Configuration options, data
files, command arguments, input, etc. are all only to select what path of
execution to use.

This probably makes about as much sense as "you hold the function up to
the data" :)
