[Pharo-users] [exercism bowling challenge] Is there a better way to do this

[r.wobben--- via Pharo-users]

Hello, 

To come back at this one.

I made a class Bowling and a class Frame which contains two instance variables 
named firstThrow and secondThrow. 

but I still wonder how do I know which one to fill in.

I can do \` (firstThrow nil?) \`  but that feels not right.

\
Is there a more idiomatic solution for this ?
