[julia-users] Strange behavior with docstring

[Eric Forgy]

Hi,

I am stumped on this one...

I'm working on a package and, for the life of me, couldn't find my bug. So, 
on a hunch, I started commented out my docstrings one by one. I kept 
getting the error until I commented out the very last docstring and then 
the code worked as expected. So the source of my error is the docstring?

Here's what it looks like:

"""
Callback used for blocking Julia control flow until notified by the 
WebSocket.
"""
Callback("notify") do name
    if haskey(conditions,name)
        notify(conditions[name])
    else
        error("""Condition "$name" was not found.""")
    end
end
# This is line 50 in callbacks.jl

This is the last code snippet in an included file. Running it, I get the 
following error:

julia> using Pages
ERROR: LoadError: LoadError: MethodError: `argtype` has no method matching 
argtype(::ASCIIString)
 in include at boot.jl:261
 in include_from_node1 at loading.jl:320

expression starting on line 50
while loading C:\Users\Eric Forgy\.julia\v0.4\Pages\src\Pages.jl, in 
expression starting on line 56

If I comment out that last docstring, everything works as expected.

julia> using Pages

julia> Pages.start();
Listening on 0.0.0.0:8000...

julia> include(Pkg.dir("Pages","examples","examples.jl"));

Any ideas?
