factories

gorillib/factories (WIP -- NOT READY YET) -- efficient, predictable type conversion

• Is a missing value unset? or nil?

• (Boolean)

• String Symbol

• Regexp

• Bignum Integer Numeric

• Float (Double)

• Complex Rational

• Random

• Time

• Date

• Dir File Pathname

• Whatever -- alias for IdentityFactory

• Method, Proc

• Range

• Hash

• Array

• Object

• Class Module FalseClass TrueClass NilClass

These don't have factories because I can't really think of a reasonable use case

• DateTime Struct MatchData UnboundMethod IO Enumerator Fixnum Object File::Stat StringIO

These are not decorated because it's not a good idea

• BasicObject

• Exception Interrupt SignalException SystemExit

• Encoding Data Fiber Mutex ThreadGroup Thread Binding Queue
