Testing symbol escape characters

[jcubic]

This is an extension of Extending Empty symbol concatenated survey
and Reader: Vertical Bar Concatenated With Number surveys

I was playing with handling different ways of escaping symbols. I came up with this test:

(write (map symbol->string '(|name| name|| name|\|| name|\\|xxx name|\\\\| name|\\|)))
(newline)

• Kawa ("name" "name" "name|" "name\\xxx" "name\\\\" "name\\")
• Gauche ("name" "name" "" "name" "|" "name" "\\" "xxx" "name" "\\\\" "name" "\\")
• LIPS (not yet released) ("name" "name" "name|" "name\\xxx" "name\\\\" "name\\")
• Chicken ("name" "name" "name|" "name\\xxx" "name\\\\" "name\\")
• Gambit ("name" "name" "" "name" "|" "name" "\\" "xxx" "name" "\\\\" "name" "\\")
• Biwa ("name" "name||" "name|\\||" "name|\\\\|xxx" "name|\\\\\\\\|" "name|\\\\|")
• Chez Scheme (9.6.4) reader get confused

So Kawa, LIPS (next beta release), Chicken handle escapes as part of the symbol
Gambit, Gauche works the same and return different symbols.

I can create a survey file, but I don't have more implementations on my system to test.
