Daniel Chandler defines the term as "a signifier with a vague, highly variable, unspecifiable or non-existent signified". [4] The concept of floating signifiers originates with Claude Lévi-Strauss, who identified cultural ideas like mana as "represent[ing] an undetermined quantity of signification, in itself void of meaning and thus apt to receive any meaning".
Python uses the following syntax to express list comprehensions over finite lists: S = [ 2 * x for x in range ( 100 ) if x ** 2 > 3 ] A generator expression may be used in Python versions >= 2.4 which gives lazy evaluation over its input, and can be used with generators to iterate over 'infinite' input such as the count generator function which ...
There is a 'barrier' of repression between Signifiers (the unconscious mind: 'discourse of the Other') and the signified […] a 'chain' of signifiers is analogous to the 'rings of a necklace that is a ring in another necklace made of rings' […] 'The signifier is that which represents a subject (fantasy-construct) for another signifier'. [9 ...
A sign's ground is the respect in which the sign represents its object, e.g. as in literal and figurative language. For example, an icon presents a characteristic or quality attributed to an object, while a symbol imputes to an object a quality either presented by an icon or symbolized so as to evoke a mental icon.
Evidence that this is the correct view comes from the fact that each language can encode signifiers with whichever signified they wish to communicate. Hence, for example, the letters comprising "air" signify what humans breathe in English, and what fish breathe in Malay, i.e. water.

In a language with exceptions, a natural type for the raise construct is raise ∈ exception -> Bot, and similarly for other control structures. Intuitively, Bot here is the type of computations that do not return an answer. Bot is useful in typing the "leaf nodes" of polymorphic data structures. For example, List(Bot) is a good type for nil.
The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
