IMC vs. PIR Two names enter One name leaves /me giggles -- Chip Salzenberg
All Parrot_char_is_* functions from src/string_primitives.c will be removed. Please use Parrot_string_is_cclass() instead.
PGE::P6Rule is now a registered compiler, and should be used like so:
<@pmichaud> it's easy; instead of $P0 = find_global "PGE", "p6rule" one now does $P0 = compreg "PGE::P6Rule"
This syntax is also true for PGE::Glob and PGE::P5Regexp
Not yet deprecated, but it's recommended to use the new syxtax and gradually change the old.
Subroutine attributes will use the colon syntax:
.sub foo method, @MULTI(x,y) => .sub foo :method :multi(x,y) .sub foo @ANON, @LOAD => .sub foo :anon :load
The new syntax uses no comma separators and all sub attributes are lower case and prefixed by a colon.
... will require a dot in front
$P0 = new Integer => $P0 = new .Integer
When the first argument of an opcode is OUT, then the assignment syntax will be allowed, as it is today.
OUT
In any other case (i.e. INOUT, IN), this will become a syntax error. For example:
INOUT
IN
$S0 = print $P0 = substr 1, 2, "x"
Will have to be:
print $S0 substr $P0, 1, 2, "x"
Currently, = is used for both assignment and aliasing. Chip says that, once this change is in effect, we'll use the following syntax:
=
P0 := P1 # aliasing: P0 and P1 point to same PMC P0 := opcode # aliasing: P0 points to PMC returned by opcode P0 = ... # assignment: modifies P0, NO MATTER WHAT '...' IS S0 := S1 # aliasing: S0 and S1 point to same header S0 := opcode # aliasing: S0 points to header returned by opcode S0 = ... # assignment: modifies S0, NO MATTER WHAT '...' IS I0 := ... # ILLEGAL I0 = ... # assignment: modifies I0 N0 := ... # ILLEGAL N0 = ... # assignment: modifies N0
