pyparsing 3.1.1 caused problem in OpenMolcas

[ABQTrap]

Dear all,
I found that the new version pyparsing 3.1.1 may cause problem when working together with the OpenMolcas, while the older version of pyparsing ran smoothly. Pyparsing 3.1.1 couldn't recognize the EMIL keywords like ">> FOREACH" or ">>COPY" or ">>DO WHILE". Please check the linkhttps://gitlab.com/Molcas/OpenMolcas/-/issues/420.
I am new to pyparsing and OpenMolcas, so I'm not sure if this is a compatible issue.

Thanks for posting, I'll take a look at this. I'll also add OpenMolcas to the wiki list of projects that use pyparsing. (If possible, please add tests to OpenMolcas so that its parser can be tested in isolation.)
