| Tracing |
|
| trace :: String -> a -> a |
| When called, trace prints the string in its first argument to
standard error, before returning the second argument as its result.
The trace function is not referentially transparent, and should only
be used for debugging, or for monitoring execution. Some
implementations of trace may decorate the string that's output to
indicate that you're tracing.
