throw value to use with try
return value to use with try
try value on_success on_error value being either a thrown one or a returned on

compose f g returning f ∘ g
left val returning a function of 2 higher order functions: when called the left most argument is applied to val
right val works like left val but it's the right most argument which will be applied to val
flip function value returning a function taking one argument bis: calling function bis value

list:forEach list function the function will be applied to every element of the list, one after the other
list:product list returns the product of every element with the others (they must be all numbers)
list:sum list returns the sum of all the elements in the list (they must be all numbers)
list:drop list count drops the first count elements of the list
list:filter list function returns a new list filtered by function (takes an element of the list, returns a boolean)
list:map list function maps every element with the given function
list:reduce list function reduces a given list with a function taking two elements, returning one
list:take list count takes only the first count elements of the list
list:unzip list unzip a list of 2 elements lists
list:zip a b zips two lists into a list of 2 elements lists

math:abs val returns the absolute value of val
math:even val returns true if val is even
math:odd val returns true if val is odd
math:min a b returns the minimum between a and b
math:max a b returns the maximum between a and b
math:pow x a returns x to the power of a
math:sqrt x returns the square root of x
math:divs n returns the divisors of n
maths:fibo n p c returns the result of the fibonacci function performed on n (p & c are accumulators)

range a b returns a range object in [a, b[
range:forEach range function calls function on each value of range
range:filter range function filter the given range using function, taking a single argument and returning a bool
range:map range function maps every value of the range with function and returns a list of those values
range:reduce range function reduces a given range with a function taking two elements, returning one

str:toLower str returns str in lowercase
str:toUpper str returns str in uppercase
str:reverse str reverses str
str:slice str start length takes a slice of start, given a starting index and a slice length
str:split str sep splits str in multiple substrings each time the separator (a single char) is found
str:replace str pattern replace replaces pattern in str with replace

switch value tests iterates over tests, a list of of 2 elements lists: [[value function] [value function]...], when value is found in the tests, the corresponding function (no arguments) is called.
