expression where definition
Hi. The "Hugs for beginners" section of the manual has the example Prelude> take 10 fibs where fibs = ... and this indeed works. But I don't see this syntax in the grammar for Haskell; where clauses are appended to declarations, not to expressions. Is this a Hugs extension? Bob T.
Yes, that's right - this is a Hugs extension. At the
prompt-level, "<exp> WHERE <decls>" is recognised
as an expression.
