sclang allows to call methods in a “functional” style by passing the receiver as the first argument. You typically see this with control flow methods like if or while:
if (b) { ... } { ... }
is really the same as
b.if { ... } { ... }
See also Fork { ... } vs. { ... }.fork - #2 by Spacechild1
In sclang, math operators are also methods, that’s why you can use the “functional” notation.
Fun fact: this also works with class methods:
read(Buffer, s, "sounds/a11wlk01.wav")
is the same as
Buffer.read(s, "sounds/a11wlk01.wav")
