New Revision: 8504
Modified:
doc/trunk/design/syn/S06.pod
Log:
* S06: Updated built-in classes:
- bring in "uint" from S09 (boxes to Int)
- new "Buf" class to represent subscriptable byte streams
- "Arguments" and "Signature" from S02
- explicit "Scalar" container type from other places in S06

-=head1 Types
+=head1 Built-in Types
These are some of the standard type names in Perl 6 (at least this week):
+=head2 Native types
+
bit single native bit
- int native integer
- buf native 8-bit string (sequence of 8-bit integers, no Unicode)
- str native string (sequence of arbitrary integers, no Unicode)
+ int native signed integer
+ uint native unsigned integer (autoboxes to Int)
+ buf native bytes (finite sequence of "uint8"s, no Unicode)
+ str native string (finite sequence of native integers, no Unicode)
num native floating point
complex native complex number
- ref native pointer
bool native boolean
+
+=head2 Immutable types
+
Bit Perl single bit (allows traits, aliasing, undef, etc.)
- Int Perl integer (allows traits, aliasing, undef, etc.)
- Str Perl string (Unicode semantics)
+ Int Perl integer (allows Inf/NaN, arbitrary precision, etc.)
+ Buf Perl buffer (possibly lazy list of bytes, can be subscripted)
+ Str Perl string (finite sequence of Unicode characters)
Num Perl number
Complex Perl complex number
Bool Perl boolean
+ Code Base class for all executable objects
+ Block Base class for all embedded executable objects
+ List Lazy Perl list
+ Tuple Completely evaluated (hence immutable) list
+ Signature Function parameters (left-hand side of a binding)
+ Arguments Function call arguments (right-hand side of a binding)
+
+=head2 Mutable types
+
Array Perl array
Hash Perl hash
+ Scalar Perl scalar
IO Perl filehandle
- Code Base class for all executable objects
Routine Base class for all nameable executable objects
Sub Perl subroutine

Submethod Perl subroutine acting like a method

Why does uint autobox, when int doesn't?
(Or num, complex, bool or bit for that matter?)

UInt or something?

Everything seems to be moving at Pugs-speed these days :-)
But what you thought was correct.
