I have written a simmple function which (in my opinion) should always  
return False. But it returns True.

It seems that Return[False] breaks the Do loop but not returns from the
function.
I thing I don't understand,  what is defining of functions. Can somebody  
explain me this.

fun[x_] := Module[{i},
     Do[If[i == 2, Return[False]], {i, 5}];
     Return[True];
     ]
