Re: [PEPr] +1 for Math::Math_Fraction

> All operators should have spaces around them ($den=null and $n/$d). As the goal of the spaces is to improve the readibility, in some cases they could be harmful. For example IMHO: Math_Fraction($num/$gcd, $den/$gcd) looks better than Math_Fraction($num / $gcd, $den / $gcd), because you could immediately see what the arguments are. However, for most of the cases you're right. Actually I haven't found anything on that topic in the Coding Standards, I mean to put spaces around *all* operators. > Return and pass-by-ref should be removed unless you provide a compelling reason for keeping it in. If for no other functions, for reduce and simplify this should be done as it may return the passed in object *or* a new one. This could quite easily cause confusion. Is the "memory gain" factor strong enough or I really have to use references when the logic requires it - as in the "reduce" example? Kouber
