[Gretl-devel] finally disallow "=" for "==" ?

Hi, I've just noticed that the old-style "=" boolean operator has been deprecated already for 3.5 years (2017a). I suggest to declare it illegal in the next release. Somewhat related in terms of deprecation, I noticed the following problem with the old-style (and illegal) "end loop" instead of "endloop". Consider this script: <hansl> clear set verbose off loop 3 end loop # illegal if "hey" == "hey" print "hoa" endif </hansl> Run it for the first time, and gretl will complain about "end loop". Fine. Now comment out the two lines of the loop and run the script again; what I get is just an echo of the script lines with added ">" characters, but no other reaction or printout from the interpreter. (Notice that even the "clear" at the top doesn't help.) thanks sven
