Interesting.


It seems that the compiler could also suggest when different names
are confusingly similar, other than spelling, or otherwise possibly
confusing to readers. Maybe by how they sound when pronounced.


You might not want J1 and J_one in the same program.


Reminds me that the IBM OS/360 Fortran H compiler, instead of using
a hash table, uses six balanced trees. IBM suggests in one manual
that for faster compilation, one distribute names among the
six lengths. Back in the time when compilation time was more
important than readability.
