Felix operators and operator names (these need to be checked!).

A chainable binary operator such as + creates a list of subexpressions.

Assignment operators are sugar for statements, so only one is allowed.

= asgn

<- asgn

:= initialise new val

+= pluseq

-= minuseq

*= muleq

/= diveq

%= modeq

|= oreq

^= xoreq

&= andeq

let <expr> in <expr> prefix

, chain

Note that "shortcut" doesn't apply in Felix since expressions are purely functional.

|| lor chain

&& land chain

! lnot prefix

== eq binary

<= le chain

< lt chain

>= ge chain

> gt chain

<> ne chain

!= ne chain

-> arrow left assoc

case <int> of <int> unassoc

Note that + has a lower precedence than -, and * has a lower precedence than / which is unusual.

- sub left assoc

+ add chain

* mul chain

/ div left assoc

% mod left assoc

- sub prefix

+ sub prefix

** pow right (special prec rules)

& prefix

* prefix

| bor chain

^ xor chain

& band chain

~ bnot prefix

(juxtaposition) left assoc

: left assoc

. left assoc

:: left assoc

of left assoc

if/then/else/endif

match <expr> with

| <pattern> => <expr>

...

endmatch

regmatch <expr> with

| <regexp> => <expr>

...

endmatch

(fun (<arglist>):<type> = { <expr> })

(fun (<arglist>):<type> = { <statements> })

{ <expr> }

Lambda function. The return type is optional. The third form is short for (fun () = { <expr> })

(proc (<arglist>){ <statements> })

{ <statements> }

Lambda procedure. The second form is short for (proc () = { <statements> })
