Special Syntax

Gorilla has some special, flexible syntax that you need to know

---

Block

block ::= "{" statement* "}"
      |   statement

which means it is valid to not have {} if you only have one statement.

func abc() {
    a()
    b()
    c()
}

func doA()
    a()

func doB() b()

if 1 == 2
    println("NO WAY!")

---

Function calls

functionCall ::= expression "(" expression? ("," expression)* ")"
             |   doExpression
             |   functionLiteral

when the function only has 1 parameter, and you want to input an argument, you don’t have to write () around the do or fn keywords.

abc(1, 2, 3)

[1, 2, 3].each(do(i){println(i ** 2)}) # This is ugly

a better-looking code with this special syntax:

[1, 2, 3].each
    do(i)
        println(i ** 2)
# A lot better
