To peek at variable in a global module you can use:

        [ modules.peek : myVariable1 ] ;

However, please note that global module is not the module where Jamroot lives.
Each project file -- including Jamroot, every Jamfile and every *-config.jam
file is a separate module. Inside such file, the name of the module can be
obtained using $(__name__)
Definitions made with 'constant' and 'path-constant' are automatically inherited
in modules of child projects. E.g. 'constant' in Jamroot will be inherited by
all Jamfiles under that Jamroot.

Hope this helps,
