The list is much longer than expected...
Seriously, I don't think a message to gretl-devel is enough. We have to use
the email adresses given in the packages, too.
Yes, probably so.
Also, I think we should offer a little more support. A script that
catches
and perhaps even autocorrects the most common occurrences for example. As
Oleh indicated, a "=" in the same line as an "if" for example can
only mean
"==" I think (right?). (... outside of a foreign block, that is....)
The hansl parser knows what cases need fixing, but it doesn't have the
facility to change its input (or at least not so the change will be
saved). Hmm, may be worth investigating though.

OK, this one concerns me myself. What again was the suggested alternative?
Re-write the function to provide an error code?
The "catch" should be moved onto the specific built-in command or
function call that could provoke an error. And responding to this
might involve the user-function providing an error code.
