The Univac Fortran V compiler (and Athena Fortran) treated statement
functions as macros.  A side effect was that a statement-function
reference could appear in a variable-definition context if its body was
allowed in that context.  I used this a lot to "fake" structures.  It's
where I got the idea to propose "component(object)" as a structure
component reference during the percent-sign controversy during F90
