LazyPromise
/**
* A LazyPromise doesn't run its executor until .then, .catch, or .finally is called,
* or the promise is awaited.
* Unfortunately, `@endo/promise-kit`'s isPromise returns false for instances of LazyPromise.
* However, LazyPromise instances will return true for instanceof Promise.

comparison of guybedford's Secure Modular Runtimes proposal to LavaMoat
hi guybedford/
i really enjoyed your blog post https://guybedford.com/secure-modular-runtimes.html
here's some quick notes comparing your proposal and lavamoat in its current form (https://github.com/lavamoat/lavamoat)
these differences represent lavamoat currently, and can easily be changed with input from smart folks like yourself
### basic runtime structure
[exactly] "this runtime can fully restrict high-level capability access from packages for third-party code running in the same process"
[exactly] "That this runtime can support an onramp from the existing JavaScript ecosystems, which is crucial for adoption. "
const { builtinModules: builtinPackages } = require('module')
// [email protected]
const { createModuleInspector } = require('lavamoat-core')
const inspector = createModuleInspector({
// used to see if this imports builtins
isBuiltin: (name) => builtinPackages.includes(name),
// adds some notes on ses compat, etc
includeDebugInfo: true,
})
