I don't think Ray is a beginner in functional programming.

Now before I try singing old wisdom from the neighbourhood of
The Mythical Man Month ...
How will a piece of source code, your own or someone else's, and
a language with tools fit these and the market as we might think
it is now?

project size,
project duration,
forced language,
availability of programmers (need to hire?),
job changes,
programmer skills,
multiple projects at the same time,
language switching e.g. between projects every other week,
time needed for education,
documentation needs,
future modification done by others,
future modification to be done by the author,
...


A rich set of opportunities for collecting some input, if only
in order to convince ourselves that some things might have changed
in software production (due to language changes?) while others
haven't changed --for example we might get carried away by a
subjective estimate of the usability of our preferred language.
In accord with the findings of Leon Festinger (1957).
