 # Constructors
 Constructors technically are nothing but functions. They just "emulate" real constructors from other general purpose programming languages that support object-oriented programming paradigm.
 ## Int
-```
+```php
 Int(value: <int, float>)
 ```
 Creates new `int` from other `int` or `float`.
 The construction is typically used in other stdlib modules to round `float` types down.

 ## list.get
-```
+```php
 list.get(index: int)
 ```
 Returns list element of given index or throws error if index is greater than `list.size - 1`.
 
 #### Example

 lastElement = myList.get(3);

 ## map.get
-```
+```php
 map.get(key: <int, note, string, bool>)

 Returns map element associated with given key or throws an error if key doesn't exist in the map.

 ## string.charAt
-```
+```php
 string.charAt(index: int)
 ```
 Returns string's character of given index or throws error if index is greater than `string.length - 1`.
 
 #### Example
-```
