While going through the posts I had stowed away because I found them
interesting, I came along this one.
There is not a problem here, just a tiny observation.
In order to work
\doifelse{a}{\doifelse{x}{x}{a}{b}}{yes}{no}
properly it is sufficient that the inner \doifelse is of the expandable kind.
Thus
\doifelse{a}{\expdoifelse{x}{x}{a}{b}}{yes}{no}
yields the same as
\expdoifelse{a}{\expdoifelse{x}{x}{a}{b}}{yes}{no}

Dear list,
Motivated by this question on TeX.SX
https://tex.stackexchange.com/questions/370868 I was fiddling around with the
\doifelse conditionals. I noticed that most of them are not expandable, which
makes it very difficult to concatenate them. Here a simple example
\starttext
\doifelse{a}{%
\doifelse{x}{x}{a}{b}% <- evaluates to "a" but not expandable
}{yes}{no}
\stoptext
This outputs "no" even though "a" is equal to "a".
Would it be possible to substitute these conditionals by expandable ones? I
would volunteer to help make them expandable.
Cheers, Henri
