Re: Expression-local variables and 'let'

(I haven't been following this closely enough, but...)

Why wouldn't we just do the 'balance < 0' within the method?

   display(currentBalance());

   void display(Money balance){ if (balance<0){} }

or is there some suggestion we would dispatch on the parameter, in
which case wouldn't we try:

   void display(Money balance){ }
        display(balance<0){ }
        display(balance>=0){ }

Me neither, small world isn't it.

Neither am I about 'let .. in ..'
