Hello,

For a challenge of Exercism I need to check if some parenthes and brackets are balanced.

so for example

()  = true ([])  = true

but (])  is not true because the bracket has no opening bracket.

Now I wonder if I can premature end a #do:  like this

collection do: [:element | (condition with element) ifFalse: [^false]]

Have you looked at anySatisfy:

 #('the' 'quick' 'brown' 'fox') anySatisfy: [:s | s beginsWith: 'x' ]

Regards .. Subbu

yep,  i also  took a look at that one
