Hello
I want to use a function using parameters.jl. Inside REPL I simply type:
```julia
julia> called_function(param1=4, param2=0)
```
The function “called\_function” has other parameters but those have default values which are good enough for me.
However I want to create a wrapper that will take some arguments and transfer them to the called function:
```julia
function my_function( a::Int64, b::Int64, other arguments)
...
called_function(a, b) # <= How can I say that 'a' is for param1 and 'b' for param2?
...
end
```
I get an error like this:
```julia
ERROR: MethodError: no method matching called_function(::Int64, ::Int64)
```
If I specify the 4 arguments of “called\_function” I don’t need to state the name of the parameters:
```julia
called_function(4, 0, UUID("51d35f80-81ee-11ed-1a59-6be8ccc438a2"), [])
```
My fallback plan is of course to state all parameters within “my\_function”. I nevertheless would like to know how I can work around this and use default values.
Thants for your help.

Maybe `called_function(param1=a, param2=b)`?
If that doesn’t work, please post a complete, minimal example that shows the problem.

Does not work. I get the same message.
Here’s a complete example with the used package:
```julia
Pkg.add(url="https://github.com/anyonlabs/Snowflake.jl", rev="main")
using Snowflake
function my_function(a::Int64, b::Int64)
c = QuantumCircuit(qubit_count=a, bit_count=b)
end
julia> my_function(2,0)
ERROR: MethodError: no method matching my_function(::Int64, ::Int64)
Closest candidates are:
my_function(::Int64, ::Int64, ::Int64) at REPL[83]:1
Stacktrace:

Your example works for me:
```julia
julia> my_function(2,0)
Quantum Circuit Object:
id: c6f6da90-8206-11ed-1053-3bc9d78927f5
qubit_count: 2
bit_count: 0
q[1]:
q[2]:
```
The error message you have doesn’t make sense with the code, maybe try to run it all again?

@sijo
damn it! What did I do wrong? I’ll find out… eventually.
Thanks Sijo
