Seems like the function is easy to define: replaceIfEq a b c = if c == a then b else c Then the above can be written replaceIfEq Foo Bar value Or the slightly more general (in exchange for slightly more verbosity at the call site) replaceIf p r a = if p a then r else a replaceIf (== Foo) Bar value On Fri, Dec 21, 2012 at 6:46 PM, Radical <radical@google.com> wrote:
Sometimes I'll need something like:
if value == Foo then Bar else value
Or some syntactic variation thereof:
case value of { Foo -> Bar; _ -> value }
Is there a better/shorter way to do it? I'm surprised that it's more complicated to substitute a value on its own than e.g. in a list, using filter. Or perhaps I'm missing the right abstraction?
Thanks,
