hi guys, firstly this has no direct application, i'm just playing around and learning

i want to create 100 uniform distributed numbers and print them
my first attempt, just written by intuition:
[0 .. 100].map!(v => uniform(0.0, 1.0).writeln);

i found out i can't write [0 .. 100] to define a simple number range, but is there a function to do so?

Yes! iota(100)

second attempt, replacing the range with an simple array
[0,1,2].map!(v => uniform(0.0,1.0).writeln);
this does compile and run, but doesn't print anything, just an empty string, why is that?

Maybe you meant to put the .writeln outside of the parens? Since map is lazily evaluated, writeln is never called and the entire expression does nothing.
