There's a certain risk that the premature-optimization fraction will
plaster every function with const declarations, but they write
unreadable code anyway ;)

Aside from this, there's still another point: assume you have quite a
number of module-level string "constants" which you want to use in a switch.
You'd have to repeat all of their names in a "const" declaration in order
to use them this way.
