Numbers in various formats are well supported by Ruby, but, for many of them, there is no convenient shorthand for entering literal constants. Also, think about code that manipulates Times, Dates, Lat/Long coordinates, complex numbers, etc. All literals must be derived from some combination of Symbols, Strings, Floats, and Integers. So, one typically ends up with unfortunate syntax like: BigDecimal("3.14159") and chafes at the thought. What if, in a way somewhat analogous to :method_missing, Ruby had simple hooks to allow substitution of literal objects for the text of otherwise illegal identifiers? Perhaps the time is ripe to revisit this idea... http://markmail.org/search/?q=ruby-core+allowing+custom+number+literal+suffixes so that Domain Specific Languages implemented entirely in Ruby could define their own convenient, domain specific literal constant syntax without requiring changes to the core interpreter. And, arguments about the superiority of binary vs. decimal or visa-versa would not be nearly as important.
