 Hello
 As I looked to C++ extension suffing numeric literals.
 My proposal is make . in method call of numeric literal optional so we can for example write
 4i instead 4.i 
 Another application is making Time manipulations more readable like
 deadline=Time.now + 2hours
 
 Here is patch
 It should be more restrictive to disallow traps like 0xadup
