You can declare functions-in-functions.
Look at this example:
func foo
func bar
println('bar')
endfunc
bar()
println('foo')
endfunc
foo()
bar()
output:
bar
foo
bar
Also look at this example:
func first
println('first start')
func second
println('second start')
func last
println('last')
endfunc
last()
println('second end')
endfunc
second()
println('first end')
endfunc
first()
output:
first start
second start
last
second end
first end
The declared function in function is accessible from outside.
For example:
func foo
func bar
println('the bar')
endfunc
endfunc
foo()
bar()
How to make a function in function local?
You should delete the function in end of parent function:
func foo
func bar
println('the bar')
endfunc
# use the function...
func.delete(__namespace__() + 'bar')
endfunc
foo()
bar()
output:
NameError: undefined 'bar'...
