I think that's not a safe conclusion.�� We know from Igor's use of Kieran arrays for C signatures in the UFFI, and can easily extrapolate here, that arbitrary Smalltalk expressions /can/ be expressed in literal arrays.�� S expressions work for lisp.

In this particular case special casing pretty printing of literal arrays in pragmas would be all that's needed to make the code look beautiful.�� Why throw the baby out with the bath water?�� It would be so easy to make this work well.

We can try this as well. And it is far more easier to work with this expressions if they are pragma arguments, than to parse the comment to find some code within.
On the other hand, it looks much nicer if we have the examples right in the method doc. you have some text describing the method, some code, some more text about the reslt.

The only thing I'd do would be to print like this to make it clear that the argument t is a literal Array and not some magic form of code:

�� �� ��<expr: #(3 + 4) result: 7>


Yes, I would like to change this anyway, even for literal arrays for ffi, calls like

mouseStateX: x y: y
������ <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode>
������ ^ self nbCall: #( Uint32 SDL_GetMouseState ( int* x , int* y ) )

this will be reformatted to

mouseStateX: x y: y
������ <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: 'errorCode'>
������ ^ self nbCall: #(#Uint32 #SDL_GetMouseState #(#int #* #x #, #int #* #y))
