map seq and radix-tree-leaf, in pcase

[Richard Stallman]

[[[ To any NSA and FBI agents reading my email: please consider    ]]]
[[[ whether defending the US Constitution against all enemies,     ]]]
[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

In the help text for pcase, I saw information about these three
constructs, but I am not sure what they mean.

    -- (map &rest ARGS)

    -- (seq &rest PATTERNS)

    -- (radix-tree-leaf VPAT)

Perhaps I should add similar constructs, or substitutes for them, to
cond*.  Could someone please explain what they mean, and give an
explained example?
