(Sorry for the belated reply.)

Evidently, some ML variants do include eval or eval-like facilities.
When reading through the sources of the Isabelle 2002 proof
verification system, I noticed the "use_text" eval-like function which
is implemented using the following system-specific functions:

smlnj-0.93: System.Compile.use_stream
polyml: PolyML.Compiler
mlworks, mosml: use
