This, I have no problem with. Creating a structure with a reserved
word is almost like creating a structure that can't be used.

It's nowhere like ATAN which had a working behavior before the sheriff
changed it :-)

This new tag-name prohibition might have subtle effects. For example,
I think MRDFITS reads a FITS table into a structure with fields named
according to the FITS column name. If the column is named 'FOR' or
'BEGIN', then you are sunk?
