This looks cool. I am a former vim user, and I have wanted an equivalent to surround without evil. This package may fill in the need.

Talking about surround without evil, there is embrace:

Althought I’ll quietly say that mine is better.

Thanks, and sorry for the delay. Quick notes:

• "flexable" should be "flexible", "surrouding" should be "surrounding". (Maybe try flyspell-prog-mode?)
• Why not write isolate--append and isolate--push as defsubst instead of macros? Your macros expand their arguments multiple times, which could lead to multiple evaluation - read the macros section of Practical Common Lisp (free online) to understand what I mean.

In any case, I'll merge this now, but you should address the above points separately.

Thanks! I'll fix those issues. I just got my flyspell back to work again recently... I will scan for any other typos.

Fixed.
