You would like Tcl ... there include is named source ... but you can
redefine it so that the command instead does something completely
different (like using the filename as a key for a DB lookup?).

Or look at the PL/Tcl unknown support. If a PL/Tcl function contains a
call to an undefined proc but a proc "unknown" exists, the latter is
called with some extra information. In the PL/Tcl case it looks into
some tables if the proc is defined there, loads it and does the
initially failed call ... an auto-include totally transparent to you script.
