bug in incremental_transform

[jesperbv4]

If you run the mce and declare a fucntion, when calling the function the passed argument gets transformed to a record. I believe the issue is on line 288. transform_application() maps
tagged_list_to_record forcing the transformation. Tried changing it to map incremental_transform. But now i got other errors trycing to call the factorial function
"throw new Error('head(xs) expects a pair as argument xs, but encountered ' + (0, stringify_1.stringify)(xs));"
"Error: head(xs) expects a pair as argument xs, but encountered undefined"

I suspect this function to bethe cause of the second error.
line:291
function transform_operator_combination(op: TaggedListOperatorCombination): OperatorCombination {
return append(list(head(op), head(tail(op)), map(transform_component, tail(tail(op)))));

Having the same issue!

Found the solution to the issue:
In incremental_transforms sub-function "transform_operator_combination" there is a typo with the parenthesis.
to resolve this issue, switch out the return statement with the following code:

return append(list(head(op), head(tail(op))), map(transform_component, tail(tail(op))));

before, the parenthesis for the list() where enclosing the second argument map function which in turn appended the value "undefined" to the list which we see in the error message.
