module

Erg allows you to think of the file itself as a single record. This is called a module.

# foo.er
.i = 1

# Defining the foo module is almost the same as defining this record
foo = {.i = 1}

#bar.er
foo = import "foo"
print! foo # <module 'foo'>
assert foo.i == 1

Since module types are also record types, deconstruction assignment is possible.

{sin; cos; ...} = import "math"
