Clarify command parsing with #

[Kratacoa]

Not sure if this is the best way of specifying that, so corrections are welcome.

That sounds incorrect to me, decl str foo 'foo # bar'; echo %opt{foo} does echo foo # bar, or maybe you meant something different with "after the expansions are parsed"

[Kratacoa]

I meant that it's only executed, if it is, only after the expansions are parsed. But reading this again and after your observation, it's clearly poorly worded.

How about:
The parsing of strings and expansions happens before # is evaluated as commenting out the rest of the line, hence its meaning might change according to command-parsing.
