Hi All,

I'm following this lecture[1] series and stuck at the module creation section.

Even though I understand the idea of the module I can't figure out the exact syntax to module creation.

Do we have to compile the  Haskell file containing the module declaration? 

For an example:

Do I have to compile this;

                module metricCalc(.....) where ... 

in a file metricCalc.hs
