Way to access MSBuild's internal properties dictionary

[am11]

In other build systems, we can access the list of tracked variable in a given context and use it for simple debugging. e.g. CMake provides get_cmake_property(allVars VARIABLES), that sets CMake's internal dictionary tracking properties in user variable allVars, which can then be iterated for printing key/values etc.

With MSBuild, we can either use VS for high quality script debugging (of XML files), or we can use plain dumps /v:d[iag], binary log etc. However, I am looking for a more granular control over internal dictionary, which MSBuild uses to track properties' names and current values in the context. Something like:

<Target Name="MyTarget">
  <!-- while running MyTarget in a very large/complex project,
    print/dump list/snapshot of *all* properties known to MSBuild at this point
    (all props include: built-ins, environment vars, custom properties) -->
  <Error
    Message="dumping all props in simple (later-diffable) output:
%(MSBuildPropertiesDictionary.Identity): %(MSBuildPropertiesDictionary.Value)" />
