Within the body of a module definition, the special parameter thismodule refers to the current module. It is analogous to procname as used in procedure definitions, but refers to the module instance (not a name).

m := module()
    export e;
    print( `BEFORE: `, op( eval(thismodule) ) );
    e := proc()
        print( thismodule )
    end proc;
    print( `AFTER: `, op( eval(thismodule) ) );
end module:

$\mathrm{BEFORE:},e,\mathbf{module}\left(\right)\mathbf{export}e\;\mathbf{end\; module}$

$\mathrm{AFTER:},\mathbf{proc}\left(\right)\mathrm{print}\left(\mathrm{thismodule}\right)\mathbf{end\; proc},\mathbf{module}\left(\right)\mathbf{export}e\;\mathbf{end\; module}$

$m:-e\left(\right)$

$\mathbf{module}\left(\right)\mathbf{export}e\;\mathbf{end\; module}$
