Too complicated code for generating a random string?

I think map() requires a callable that receives one argument.

table() doesn't need the iota() as map(), it accepts one or more 
numerical arguments, so it's able to generate 2D arrays, 3D 
arrays, etc.:

table!(() => letters.choice)(3, 4, 5).writeln;
