+# Therefore, we should add a special case function that will handle this token.

+# This function should generate the proper expression form of the expression
+# using GDB\'s internal expression mechanism (e.g., \`write_exp_elt_opcode\'
+# and so on). It should also return 1 if the parsing was successful, or zero

+# zero means that the special parser is deferring the parsing to the generic
