[zoeyfyi]

The array syntax should be as follows

# Defines a length 5 int array
int[5] foo = {1, 2, 3, 4, 5}

# Gets the 4th element in the array
foo[3]

# Returns a slice of the 2nd to 4th elements
foo[1:3]

# Returns foo array as a vector
int<5>(foo)

• Array definition
• Array value by index
• Array set value at index
• Array to slice
• Array to vector
