Using @eval in a function

I did not know/understand this, thx.

It is similar to my second example but more clarifying, thx again.

Coming back to my initial post, how can I create a function within a function, specify it programmatically and return it?

function fun()
    foo(x::Real) = x
    f = :foo
    @eval $f(x::Complex) = x'
    return foo
end
bar = fun()
varinfo()

  –––––––––––––––– ––––––––––– ––––––––––––––––––––––––––––––––––––––––––––––––
  Base                         Module                                          
  Core                         Module                                          
  InteractiveUtils 307.688 KiB Module                                          
  Main                         Module                                          
  bar                  0 bytes (::var"#foo#1") (generic function with 1 method)
  foo                  0 bytes foo (generic function with 1 method)            
  fun                  0 bytes fun (generic function with 1 method)

I would like bar to have two methods, the ones that currently have foo and bar itself.
