How do you do that?
Moreover, all characters whose Unicode scalar values are greater than 127 and whose Unicode category is Lu, Ll, Lt, Lm, Lo, Mn, Mc, Me, Nd, Nl, No, Pd, Pc, Po, Sc, Sm, Sk, So, or Co can be used within identifiers. In addition, any character can be used within an identifier when specified via an <inline hex escape>. For example, the identifier H\x65;llo is the same as the identifier Hello, and the identifier \x3BB; is the same as the identifier λ. <URL: http://www.r6rs.org/final/html/r6rs/r6rs-Z-H-7.html#node_sec_4.2.4> Guile doesn't support the R6RS inline hex escape notation. Instead, it natively supports a notation of its own: #{foo bar}# #{what ever}# #{4242}# Or the R7RS notation: |foo bar| |\x3BB; is a greek lambda| |\| is a vertical bar| <URL: https://www.gnu.org/software/guile/manual/html_node/Symbol-Rea d-Syntax.html#index-r7rs_002dsymbols> Marko -- https://mail.python.org/mailman/listinfo/python-list
