the spaces come from the stringification of lists/arrays:

  my @array = <a b c d> ;
  say ~@array;            # "a b c d"

You can use
  say [~] @array;         # "abcd"   or
  say @array.join("");    # "abcd"   or
  say join "", @array;    # "abcd"
if you want to supress the spaces.

And you could override this by doing something like:
  class MyArray is Array {
    method *prefix:<~>  (@self: ) { [~] @self }
  }

  my @array is MyArray = <a b c d> ;
  say ~@array;            # "abcd"
