`DESCRIPTION`

- Determines the CPU-time, required to evaluate the specified pure expression.

- getCPUSeconds :: (Fractional seconds, NFData expression) => expression -> IO (seconds, expression)
- printCPUSeconds :: NFData expression => expression -> IO expression

# Functions

:: (Fractional seconds, NFData expression) | |

=> expression | Arbitrary polymorphic expression. |

-> IO (seconds, expression) | The original expression, tagged with the CPU-seconds taken. |

- Time the specified pure expression, returning the required number of CPU-seconds and the result, as a
`Pair`

. - CAVEAT: as a side-effect, the expression is
*deep*evaluated.

printCPUSeconds :: NFData expression => expression -> IO expression Source

- Print the time required by the specified pure expression.
- CAVEAT: as a side-effect, the expression is
*deep*evaluated.
