/*
 * Calling math.h functions like `floor` and `floorf` on CGFloat variables
 * becomes problematic when compiling the same code for both 32-bit and 
 * 64-bit platforms, since CGFloat is double on 64-bit, float on 32-bit. 
 * Hence, if you compile with -Wconversion set, `floorf` will give a warning 
 * on 64-bit, while `floor` gives a warning on 32-bit.
 *
 * Here's a suggested implementation of an architecture-independent `floor` 
 * function, written using plain old function overloading which is enabled 
 * using the `__attribute__((overloadable))` Clang language extension.

// I wish something like this (with a better name for the keyword):

@missing UILabel *titleLabel {
	UILabel *label = [[UILabel alloc] init];
	return label;

// Could turns into this:
