Hmm, I missed some more changes.
I'm not sure I'd want the MABlockDescription in Magritte-Model.
Perhaps a separate package Magritte-UnsafeExtensions?
"protocol: visiting-description"
MAStringReader>>visitBlockDescription: aDescription
| block |
block := Compiler evaluate: self contents.
self object: block
458 provides a better merge, without th eblock description.
Still not compatible with Pharo20 build (NumberParser)
