Access Modifiers

A function can be marked pub to expose it as an externally accessible API.

pub fn some_function():
    print "This function is accessible outside this module/file."

pub class Calculator:
    init:
        i32 this.currentval = 0

These are not accessible:

fn internal_function():
    print "This function is only accessible within this module/file."

class InternalHelper:
    init:
        i32 this.value = 42

Functions and classes without the pub keyword are private to their module or file by default. This means they cannot be accessed from outside their defining scope.
