Python does something funny: ``` $ python Python 3.5.3 |Continuum Analytics, Inc.| (default, Mar 6 2017, 12:15:08) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin Type "help", "copyright", "credits"...

Still for documentation: the [mpfr](http://www.mpfr.org/) library [treats it also](http://www.mpfr.org/mpfr-current/mpfr.html#index-mpfr_005fpow) as an exception: pow(x, y) returns NaN for finite negative x and finite non-integer y. but it has a [`root(x,k)`](http://www.mpfr.org/mpfr-current/mpfr.html#index-mpfr_005froot) function...

Sorry for my initial posting with empty description, I hit the return key accidentally on keyboard.

Pasting here the code lines from repo (my line numbers in description were pasted from hyperref.pdf) https://github.com/ho-tex/hyperref/blob/de4100b047195a1451163a8fd3c149eedd2b709b/hyperref.dtx#L12557-L12564

@touhami actually `\l@section` in article class adds it own group scope (cf [my comment to the tex.sx question linked-to next](https://tex.stackexchange.com/questions/427029/color-change-in-toc-addcontentsline-shows-up-in-pdf-bookmarks#comment1068568_427048)), which allows some abuse like `\section{A \color{red} B}` although this...

@touhami besides, at https://github.com/ho-tex/hyperref/blob/de4100b047195a1451163a8fd3c149eedd2b709b/hyperref.dtx#L12549-L12552 there is no hyperlink added, and despite this the `#2` is not enhanced with braces.

BTW, regardnig [etoc](http://www.ctan.org/pkg/etoc) I added a workaround at release ``v1.08p [2018/07/04]``
