That makes sense. readln includes the newline:

$ echo hello | rdmd --eval 'readln.map!(std.uni.isWhite).writeln'
[false, false, false, false, false, true]

You can use std.string.chomp to drop it:

$ echo hello | rdmd --eval 
'readln.chomp.map!(std.uni.isWhite).writeln'
[false, false, false, false, false]
