    912Note that Sysel syntax is not finalized. Some important language features are missing at the moment (especially visibility control and packaging) so the examples presented will need to change when these are implemented.

    11 This article currently serves several purposes. First as a memo, not to forget ideas and elaborations. Second as a temporary source of information for anyone who wants to learn about Sysel (and plans for it). Third by sharing the plans to allow discussion and brainstorming.

    5455Ideally NNPS should compile natively in POSIX, cross-compile from POSIX to HelenOS and ''eventually'' compile natively in HelenOS. The ''eventually'' is there because an appropriate backend (i.e. a C compiler) needs to be ported to HelenOS before native compilation is feasible.

     57NNPS will be bootstrapped using SBI. That is by running SBI(NNPS(NNPS)) we will obtain a binary version of NNPS. This process will presumably require 'significant' computing resources since SBI is rather slow and consumes a lot of memory. Once compiled to binary form, NNPS should be much more modest.
