Thank you, Kissaki, for the crossposting :)

Thank you for your very useful feedback :)

A native representation of HTML tags is a good idea: I'll have to do that.

For ...---, I wanted a big split symbol between branches (||========) and a small split symbol between the two steps inside a branch (...---). ... because the branch continues and --- to mark a smaller split than ==========.

I intend to add a syntaxic sugar for:

parallel(select N) ||
||==============
	myFunction(arg1,...,argM)
...--------
	restOfBranch1
||=============
	myFunction(arg1b,...,argMb)
...-------
	restOfBranch2

that would be:

choose N by myFunction
	* arg1,...,argM
		restOfBranch1
	* arg1b,...,argMb
		restOfBranch2

Thank you for your feedback, which lets me know that you enjoyed the playground. :)

Thank you! I look forward to hearing your opinion.

Thank you very much for your feedback. 🙂
