Even though technically Mythryl does not determine whether an identifier is infix or not based on its syntax, in practice Mythryl like most languages uses non-alphabetic identifiers primarily as infix operators. Some of the default bindings include:
+ # Addition, both integer and floating point.
- # Subtraction, both integer and floating point.
/ # Division, both integer and floating point.
% # Modulus, both integer and floating point.
| # Bitwise 'or', integer.
& # Bitwise 'and', integer.
^ # Bitwise 'xor', integer.
Unlike languages such as C, these are simply default bindings which may be readily overridden by the application programmer. (For one example of doing so to good effect see the Parsing Combinators I tutorial.)
Mythryl non-alphabetic identifiers have the syntax
[\\!%&$+/:<=>?@~|*^-]+
which is to say basically any string of ascii special characters other than
( ) { } ; , . " ' ` _ #
Some non-alphabetic identifiers are reserved and not available for programmer use as vanilla identifiers:
. # Used in record.field syntax.
: # Used in var: Type syntax.
:: # Used in package::element syntax.
! # Used in head ! tail syntax.
= # Used in pattern = expression syntax.
== # Used in expr == expr syntax.
=> # Used in pattern => expression syntax.
-> # Used in Type -> Type syntax.
?? # Used in boolexp ?? exp :: exp syntax.
&= # i &= j is shorthand for i = i & j.
@= # i @= j is shorthand for i = i @ j.
\= # i \= j is shorthand for i = i \ j.
$= # i $= j is shorthand for i = i $ j.
^= # i ^= j is shorthand for i = i ^ j.
-= # i -= j is shorthand for i = i - j.
.= # i .= j is shorthand for i = i . j.
%= # i %= j is shorthand for i = i % j.
+= # i += j is shorthand for i = i + j.
?= # i ?= j is shorthand for i = i ? j.
/= # i /= j is shorthand for i = i / j.
*= # i *= j is shorthand for i = i * j.
~= # i ~= j is shorthand for i = i ~ j.
++= # i ++= j is shorthand for i = i ++ j.
--= # i --= j is shorthand for i = i -- j.
