Loop over function names to document them

You also need to @eval the call to @doc.

Here is an MWE, based on your example:

fdocs = Dict(
    :foo => "returns 1",
    :bar => "returns 1 also"
    # etc.
)

for (f, docstring) in fdocs
    @eval $f() = 1
    @eval @doc $docstring $f
end
help?> foo
search: foo floor pointer_from_objref OverflowError RoundFromZero unsafe_copyto!

  returns 1

help?> bar
search: bar baremodule SubArray GlobalRef clipboard BitArray backtrace BitMatrix

  returns 1 also
