The data displayed below is derived from the YAML file core-properties.yml

Fixity

function

Effect: the function head is voiced followed by a connector such as "of" or "applied" to, followed by the arguments separated by connecting words such as "comma" or "and"

Applicability: intent function head

f:function(x,y)

English: f of x comma y

English: f of x and y

French: f de x et y

prefix

Effect: the function followed by the arguments are voiced, with no connecting words.

Applicability: intent function head

f:prefix(x,y)

English: f x y

postfix

Effect: the arguments followed by the function are voiced, with no connecting words.

Applicability: intent function head

f:posfix(x)

English: x f

infix

Effect: the arguments are voiced, separated by the function, which may be repeated if there are more than two arguments.

Applicability: intent function head

f:infix(x,y)

English: x f y

silent

Effect: the arguments are voiced with no connecting words. The function head is not read.

Applicability: intent function head

f:silent(x,y)

English: x y
