The psychology of programming people have incontrovertible evidence
that the very best programmers are able to work to a high level in many
different programming languages (there are many references for this,
see the work by Petre, Green, Sharp, etal.). The hypothesis that
learning to a real working level a new language increases competence on
all previously known language that you still have working knowledge of
is also proven. However there is a caveat, that the new language must
have a new computational model or at least a significant breaking
change in something associated with the computational model. So if you
know C then learning Haskell has great benefit. Then learning List has
great benefit. But then learning Scheme will have little benefit.
Learning C++, then D, then Rust for example will have benefit because
there are new things there even though the core computational model is
effectively the same – they have differences that matter.
