Cannot `convert` an object of type String to an object of type Symbol

[arseny-sandaar]

Hello,

the convert() function does not work. I could not find how to use it correctly.
Was it changed?

julia> convert(Symbol,"a")
ERROR: MethodError: Cannot `convert` an object of type String to an object of type Symbol

Please ask questions on discourse.julialang.org or Slack channel.

convert is used when two things "essentially the same thing (1.0f, 1.0, 1)" (in other words, you're just changing the representation of it).

In this case, you want to do Symbol("a")
