891	"args egg: can't use an option called ""name"""	dreamtime	Jim Ursetto	"When using the args egg, trying to use an option called ""name"" fails because of a conflict with the args egg's own internal ""name"" variable.

From the args egg documentation:  ""BODY is an option-processor as defined in SRFI 37, and has access to the variables OPT (the current #<option>), NAME (the option name) and ARG (argument value or #f).""

At line 12 in the code example given below, everything works as intended, with the ""name"" variable being set to ""foo"" when the program is called as:  ./myprogram.csi --name=foo

But after line 19, the ""name"" variable is empty again.

If the ""name"" variable is changed from ""name"" to anything else, like ""xyz"", it works.
