[Newbies] How to put a block into an Array

Newbie here, working my way through Guzdial's Squeak: Object-Oriented Design with Multimedia Applications (2001). One of the exercises requires building an Array with a block of code as an element, the idea is to lookup the stored block in some way and execute it. But, how do you store a block of code in an Array?

For example, I can do this:

[Transcript show: 'a message'] value

But I can't get this to work:

myArray := #([Transcript show: 'a message']). (myArray at: 1) value

The reason is that (myArray at: 1) doesn't recognize the stored object as a block. Inspecting it shows the odd symbol: #[ ??

Can someone get me back on the clue train?

Thanks,

David
