the code with some annotations. It should be pointed out that the code is 
only designed to deal with C types)

// If the  variable is a C-string, print it as such
static if(is(a == char*))	writef(`, "%s"`, t[i][0..strlen(t[i])]);

// if the variable is implicitly castable to int print it as such
else static if(is(a : int))	writef(", %d", t[i]);

// otherwise print the type name and the value (hope write can deal with it)
else	writef(", [%s]%s", a.stringof,t[i]);
