Those don't have verb forms. You might think you're simplifying things by doing this, but you wind up with "dollarize" and "caretify" and such.
But even more fundamentally: the characters don't go away. You still have to talk about underscores and dollars and such as literals, or in strings...
>> second "a@b"
== #@ ; an AT, not a PIN
>> second [a @ b]
== @ ; a PIN, not an AT
>> @
** Error: @ is missing its argument to take literally
>> @ foo
== foo
>> #@
== #@
The evaluator behavior of "at" is to evaluate to an "at". A "pin" does something different when it stands alone than when attached to something, but I still call it a pin.
[_ #_ @ #@ $ #$ ^ #^ ~ #~]
"A BLOCK! with a Space, an underscore, a Pin, an "at", a Tie, a dollar, a Lift, a caret, a Quasar, and a tilde in it.
What's particularly clever here now is that what would be (#" ") renders as _ so it really is a SPACE, not an underscore or a "blank".
>> second "a b"
== _
Calling that an underscore is clearly wrong. Once you understand why that's clearly wrong, you should understand why calling the rest by their visual representations is wrong too.
I'm suggesting _ be a "space rune" if one needs to speak precisely. Though context should usually be sufficient to not need to differentiate from the space character as applicable writ large.
Honestly...
To be honest, it's times like these that my avatar's glare is quite deserved.
This is world-class work, and shouldn't be equated to nonsense.
