That seems unwise advice to give unqualified. Every time you instance a 
source location you add the path of your source file to your binary, 
which bloats your binary.

The same occurs when people use __FILE__ everywhere and think it cost 
free. It isn't.

What I like about stacktraces is that they are genuinely cost free if 
you can ensure they are only collected when useful, albeit they can lack 
essential detail sometimes if the optimiser does too well.
