a few ruby-root questions

hi,

i have a few ruby-root questions:

1. is there a way to call static member functions of classes? for example, how would i use TMath::Prob, the ruby-esque TMath.Prob(chi2,ndf) doesn't work.
2. is there a good way to deal with arrays of strings? it's nice how TArray's/TList's are converted to ruby arrays...but i can't store string or char* in these since anything in a TList must derive from TObject.
3. knowing this would answer #2...is there a way to simply return the VALUE object created in pure C code? i tried to include ruby.h when generating a dictionary and it gave lots of errors. what i can do is define a member method like:

void foo(const char *__var);

then include the ruby.h file in the classes .C file (keeping it away from cint) then use the rb_ary_new etc...to fill an array with strings,floats,etc. and then use rb_gv_set to set a variable named __var on the ruby side to be the array. this works, but isn't the way i want to have to call things. if i knew how to simply return the VALUE object, then i could just fill the arrays myself.

just to note, since i couldn't include the ruby.h file without getting lots of errors...i tried simply copying the VALUE typedef (which is unsigned long) into my classes .h file. this compiled and ran, however the VALUE ruby array ended up as just an integer (bignum) on the ruby side...so it was just an unsigned long.

thanks.
