In the § More complex examples section above, calc is used in two senses, showing that there is a Haskell type class namespace and also a namespace for values: a Haskell type class for calc. The domain and range can be explicitly denoted in a Haskell type class. a Haskell value, formula, or expression for calc.

1 2 3 Case-expressions in Haskell and match-expressions in F# and Haskell allow both switch-case and pattern matching usage. ^ In a Ruby case construct, regular expression matching is among the conditional flow-control alternatives available.
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
The assignment a = b is an expression that evaluates to the same value as the expression b, with the side effect of storing the R-value of b into the L-value of a. This allows multiple assignment: This allows multiple assignment:
Hugs (Haskell User's Gofer System), also Hugs 98, is a bytecode interpreter for the functional programming language Haskell. Hugs is the successor to Gofer, and was originally derived from Gofer version 2.30b. [1] Hugs and Gofer were originally developed by Mark P. Jones, now a professor at Portland State University.

Regular languages are a category of languages (sometimes termed Chomsky Type 3) which can be matched by a state machine (more specifically, by a deterministic finite automaton or a nondeterministic finite automaton) constructed from a regular expression. In particular, a regular language can match constructs like "A follows B", "Either A or B ...
