Testing whether an object is string-like.
Problem
You have to test if an object is a string, or string-like.
Solution
Use the built in method isString. Evaluate the following lines in Dolphin Smalltalk to see how it works.
'Hello World!' isString.
$A isString.
This also works for user defined sub-classes of String, as demonstrated in the next code segment which should be evaluated in Dolphin Smalltalk.
| aString |
aString := MyString new.
aString isString
