Many thanks for the suggestions.
The use case I had in mind is more along the lines of what Peter
Dalgaard mentioned, and his solution looks ideal. I know in advance
exactly what code I want to run, but some of that code may require
user input.

For an alternative approach to your original goal, take a look at
demoSource() in the SoDA package from CRAN. It's a bit tedious to set
up (see the Details section of the help file) but uses standard R
sessions to mix lines from a demo file and interactive input.
