Compile-Time objects

See Also: S06 

The compile-time system builds a 'Program' object.

"$program" stringifies to compiled code.

Environment

- contains the declarations in scope: variables, subroutines
- maybe contains also 'want'.

Methods

."" (overloaded stringification) - stringifies to source code
.box - creates a boxed object. Example: int.box -> Int
.WHAT - returns the class as a Class (which stringifies to the class name)
.perl - returns a Str, which contains the object dumped as Perl6 source code  

Coercions

.str .num .int .bool
.array .hash .scalar

Class-specific operations - for example:

.print - returns the code to execute '.print'
.true
.not
.== (encoded to ASCII, as '_61__61_')
.eq

Special Classes

These classes are used internally to optimize the implementation, by moving boxing and type-checks to compile-time.

(Type)Scalar - a typed Scalar
  ArrayScalar
  HashScalar

(Type)Seq - a typed Seq 
  ArraySeq
    - An Array that doesn't contain Lazy components. This can be represented by a Perl5 Array.
  HashSeq

(Type)Expression - a typed expression
  AnyExpression 
  BoolExpression
  IntExpression
  StrExpression
  ...
  ArrayExpression
  HashExpression

Perl5Scalar - '$a'
  A Scalar called by name

Perl5Array - '@a'
  An Array called by name

Perl5Hash - '%h'
  A Hash called by name

(TODO)
  A Hash that only has Stringified keys. This can be represented by a Perl5 Hash.
