where a mma function takes a function as an argument, eg: Select[expr,f] and "f" is a simple function say f[x_] := x < 0 is there a way to define the function directly in the argument list? something like: Select[expr, arg < 0] of course that doesnt work, but it seems like an issue if figuring out the syntax.. ==== [MESSAGE SEPARATOR] ====
