What do you mean by "the ratio for allowing such constructs"?

I see.  But does Fortran have the FOR keyword?  I've just had a look and been
reminded that Fortran uses DO for for-loops - none of the online sources I've
found mention FOR as alternative syntax.  But it seems to me that the cause of
this was a failure to test the software properly - something that is needed
regardless of what language it is written in.
