Hi all,</p>

I'm currently trying to implement #parseNodeWith: on SyntaxMorph, in order to embed SyntaxMorphs into regular tiles. (Did this ever work in past?)</p>
<p style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
I'm afraid the attempt in the commit below does not work yet; you can create a script editor, but parsing is erroneous, so you cannot execute the script.</p>

I don't know how to use #generate: exactly, but other senders usually appear to recompile a method before passing it to #generate:.<br>

<p style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
Why is that recompilation required but decompilation is insufficient? Is this some bug, or is it expected behavior?</p>

However, in the case of SyntaxMorph, I don't know how to recompile the node before, as a SyntaxMorph should be able to represent a node of an arbitrary type that must not be constrained to a MessageNode. So how could I solve the problem to generate code from
SyntaxMorphs?</p>

<p style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
tl;dr: What is the full story of #generate: and how can it be made to work in this example?</p>
<p style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
