{{task}}
'''Task:''' Create a list of 10 functions, in the simplest manner possible ▼
;Task:
(you may choose to start <math>i</math> from either 0 or 1), when run, ▼
▲(you may choose to start <big><math> i </math></big> from either 0 or 1), when run,
should return the square of the index, that is, <big><math>i^2</math></big>.
Display the result of running any but the last function,
to demonstrate that the function indeed remembers its value.
;Goal:
In imperative languages, one would generally use a loop with a mutable counter variable.
For each function to maintain the correct number, it has to capture the ''value''
of the variable at the time it was created, rather than just a reference to the variable, which would have a different value by the time the function was run.
