EXAMPLES:
methods <- expression(lsfit(x, y), l1fit(x, y))
all.names(methods)
# produces the following output:
[1] "lsfit" "x" "y" "l1fit" "x" "y"
all.names(all.names, unique = T)
# produces the following output:
[1] "T" "F" "z" ".C" "list"
[6] "expr" "as.integer" "functions" "character" "max.names"
[11] "vector" "unique" ">=" "$" ">"
[16] "*" "x" "length"
