Feature #4007
closednumeric literal syntax sugar
Description
=begin
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

activesupport already gives us stuff like
Time.now + 2.hours
is typing the dot really that much extra work for you?

Some suffixes for number literals, such as 4i
and 4r
, were introduced as a custom syntax. Please reopen if you still want a general framework for number suffixes.
