is it possible to extend Bolero HTML Builder CEs with `CustomOperation`? about bolero HOT 3 CLOSED

On the contrary, you should be able to augment Bolero.Builders.ElementBuilder with your own custom operators/keywords, following the same convention as for the built-in set. To provide type safety, i.e. where certain features are only available inside a given custom operator like in your example above, you will need extra sub-builder types and quite a bit of boilerplate code. Overall, not a whole lot of gain for a small improvement of notation, but if you do it well (with inlining, etc.) you might just make it more performant than ordinary function calls.

That said, I'd strongly advise against encoding HTML components in F# and use templating instead.

Looks like the answer is no:

...computation expressions and custom operators are two orthogonal language features that do not interact in any way...

thanks @granicz! ... i have opened a SO question to get a better understanding of CEs

with regard to templating, i would be interested in a templating approach where we have something like haml or pug to avoid the verbosity
