There is a file data.txt with numbers: 345 5467 45 238 ... And I want to load into an array of uint like this. auto sizes = map! (to!(uint, string)) (compose!(split, q{cast(string) std.file.read(a)})("data.txt")); It works but cast is always bad ^_^. How can I eliminate cast? Is there function to read entire text file in string? Thank you, Dee Girl
