Perl6 Operator List, Take 2

[Michael Lazzaro]

Here's try #2. Things that are not true operators or have other caveats are marked, where known. LMKA.


unary (prefix) operators:

\ - reference to
* - list flattening
? - force to bool context
! - force to bool context, negate
not - force to bool context, negate
+ - force to numeric context
- - force to numeric context, negate
~ - force to string context
. - method call on current topic

++ - preincrement
-- - predecrement

unary (postfix) operators:

++ - postincrement
-- - postdecrement

other postfix operators:

() - [when operator is expected]
[] - array access
{} - hash access

hyperoperators:

^ - as prefix to any unary/binary operator, "vectorizes" the operator


binary operators:
+ - * / % ** x xx ~
+= -= *= /= %= **= x= xx= ~=

< > <= >= == != <=>
lt gt le ge eq ne cmp

&& || !! // - boolean operations
&&= ||= !!= //=
and or xor err

.& .| .! << >> - bitwise operations
.&= .|= .!= <<= >>= - (or is that .<<, .>>, etc?)

& | ! - superpositional
all any one (none?)

~~ !~ - smartmatch and/or perl5 '=~' (?)
like unlike - (tentative names)

=> - pair creator
, - list creator
; - "lesser comma", list-of-lists creator
: - adverbial
. - method call

.. - range
... - (maybe range exclusive of endpoint, or maybe ..Inf)

= - assignment
:= - binding
::= - binding, but more so

trinary operators:

?? ::

parens, misc, and quotelike operators:

()
[] - [when term is expected]
{} - [when term is expected]

m// - shorthand for something else
s/// - shorthand for something else
tr/// - shorthand for something else

'...' "..." `...` /.../ << >>
q qq qx qr qw

(heredocs) - [exact format unknown]


named unary (prefix) operators, terms, and other assorted hangers-on, identified when possible:

-X - [op] filetest operators

temp - [op]
let - [op]
ref - [op]
defined - [op]
undef - [op]
undef - [term]
exists - [op]
delete - [op]

${ } - [deref] dereference scalarref
@{ } - [deref] dereference arrayref
%{ } - [deref] dereference hashref
&{ } - [deref] dereference coderef

... - [term] yada**3
Inf - [term]
NaN - [term]

is - [declar] var properties
but - [op?] val properties
-> - [declar] like 'sub'
hash - [declar] force hash context


methods and listops, uncategorized:

my our
map grep
sqrt log sin cos tan
lc lcfirst uc ucfirst
int ord oct hex (bin?)
