I'm not sure what Steven is claiming here.
 
Is he claiming that ":=" vs "=" is a greater visual distinction than "=" vs
".EQ."?
  
Is he claiming that the Algol distinction is easier to parse than the Fortran 
one?
 
After all, the discussion was about what Algol brought that was new.  The
distinction between assignment and comparison certainly wasn't new, the only
new thing here is the particular concrete syntax:  so what's so great about
this particular concrete syntax?
 
Or is Steven, like most of those who claim that Algol brought new concepts
into the computer language area, just totally ignorant of what went before?
