Tap dance instant press?

[haasn]

I'm trying to configure the "tap dance" behavior in such a way that it will trigger tapped keys instantly, rather than waiting until "tapping-term-ms" has elapsed; but it doesn't seem to be possible currently. Each subsequent tap should simply produce the next keypress in sequence:

Some examples of usage could include:

• Giving ( on the first press, and ) on the second press
• Giving q on the first press and u on the second
• Enabling sticky shift on the first press, and caps_word on the second
• Emitting LC(S) on the first press and LC(Q) on the second one (this is the use case that motivated this feature for me)

Tangentially related to #2042, which could be used to implement this functionality in simple cases. Also a duplicate of #1979, which was prematurely closed despite no resolution being offered.

I guess #1979 wasn't clear enough about the eager tap behavior given both Joel and I missed the distinction. While this sounds like it can be achieved via a macro with tap+sticky layer, it seems reasonable to me to add it as a flag to tap dance.
