[julia-users] let and named args

[Michael Francis]

I was somewhat surprised to find that name args do not have an implicit let 
and I don't seem to be able to embed the let syntax

bar() = "Hello"
wow( ; bar = bar() ) = string( bar, " world")
wow()
: ERROR: bar not defined

Within a function I can do the following 
function foo()
  let bar = bar()
    return string( bar, " world" ) 
  end
end
: foo (generic function with 1 method)

In the args I can not do so ( perhaps there is a working syntax ? )
wow( ; let bar = bar() end) = string( bar, " world")

: ERROR: syntax: invalid keyword argument syntax "(let (block) (= bar (call 
bar)))" (expected assignment)

Thanks
