# it's posible to simplify two identical calls into one. Example:

# Not stable.
# Not stable. This flag IS implemented.
#
# variable:
# Not stable. Alias for unstable.
# strlen:
# Marks the function as accepting one unique parameter of type string,
# and returning 0 is equivalent to the parameter being an empty string.
#
# detect:
# Marks the function/event as being a detection one.
#
# touch:
# Marks the event as being a touch event.
#
# grab:
# Marks the event as enabling grab detection.
#
# delay <value>:
# Function has a delay.
