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
