REPL help ? fuzzier / startswith matching

[chris-b1]

This is a relatively minor workflow thing, but has happened to me enough times to raise this

Sometimes partially through typing a function call I want to access help, but it doesn't work with a partial parameter list. E.g.

julia> my_function(param_a, param_b   # stop, what is the param order again?

# <home> back to beginning of call and enter a ?

help?> my_function(param_a, param_b 
search:

Couldn't find 'my_function(param_a, param_b'
Perhaps you meant my_function
  No documentation found.

  Binding 'my_function(param_a, param_b' does not exist.

#  need to delete off of the partial parameter list

help?> my_function
search: my_function

  my documentation

I think it could be non-ambigous to search help based on function names with a partial parameter list?
