Gstrings

[Dirk Laurie <dpl@...>]

Generalized strings (gstrings)

    A gstring g is a list whose string representation is the 
    concatenation of the string representations of its values, 
    joined by g.sep.  Other 'pairs' values of g are irrelevant.

Example:
    t=gstring({true,'false'},'/')
    print(gstring({0,t,math.sin},', ')) --> 
0, true/false, function: 0x93e0700
    z={1,{2,3},{{4,5},{{6,7,8},9}}}
    print(gstring(z,{'\n', "   ", ' + ', "*"})) -->
1
2   3
4 + 5   6*7*8 + 9

If all separators are empty, a gstring is a rope, see e.g.
