I don't get it. The line "bool result = (a == b);" can surely be
optimized away as it has absolutely no effect.

Following that optimization, the rest of the code turns into

bool didThisCompare(T)(T a, T b, bool performComparison)
{
     if (performComparison) return true;
     else return false;
}

...which is the same as...

bool didThisCompare(T)(T a, T b, bool performComparison)
{
     return (performComparison) ? true : false;
}

...which is the same as...

bool didThisCompare(T)(T a, T b, bool performComparison)
{
     return performComparison;
}
