Re: Add support for arbitrary code inside template tags without the 'do' keyword

A use I thought up (although I got lazy and abandoned it later) was an `exec` template tag, for executing commands. Or, and this just came off the to of my head, you could use it as a vdom library as almost like a Lisp reader macro: ```js n`.form-ctrl`( n`input#input`("input"),

Re: Promises as Cancelation Tokens

*F# cancellation* - on second thought implicit cancellation through cancellation like in F# is impractical because of the eagerness of promises. I don't think it's a valid alternative here. I've discussed this with Reed Copsey (an F# expert) and he explained the philosophy behind it to me - it

Re: Add support for arbitrary code inside template tags without the 'do' keyword

Problem is: your idea has already been tried and found to be pretty slow. React devs did briefly consider this, but found that it had fundamental speed limitations. And precompilation is already happening with existing templates, even though building them normally is still cheap to do.

That link details other reasons, such as tooling. On Wed, Jan 13, 2016, 18:11 Isiah Meadows wrote: > Problem is: your idea has already been tried and found to be pretty slow. > React devs did briefly consider this, but found that it had fundamental > speed limitations.
