Idiom # 245: Print value of custom type

See programming-idioms.org:

Code

say x     # it usually helps if x's type redefined 'as_string'

What are effects?

Running Example

ex245 is

  T1 is
    a := 42
    b := "Hello"

  x := T1
  say x

  # output is much more useful if as_string is redefined
  T2 is
    a := 42
    b := "Hello"
    redef as_string => "T $a $b"

  x := T2
