# V has memory management strategies, in default it will be [DYNAMIC][FUNCTION]
# Which means it's static, but it will be auto released as the function is ended
# Others are:
[FUNCTION] # FUNCTION wide
[GLOBAL] # global wide

[STATIC] # keeps the value until program stops
[DYNAMIC] # dispose the value ASAP
[USR] # memory managed by users
