Unexpected parse error inside deno REPL

[Shifta-Robel]

This piece of code

> function mergeSort(arr){
     if( arr.length <= 1) return arr
     let left = mergeSort( arr.slice( 0 , arr.length/2 ) )

keeps giving parse error: Expected '}', got '<eof>' at 3:50, can't seem to go past it without using Ctrl+S.
And it works fine in node

Minor clarification: The issue is that Deno's REPL doesn't automatically insert a line break with this input but instead tries to interpret the whole code as a complete command, which it is not as it is missing the closing brace for the mergeSort function.

Node's REPL correctly infers that an Enter press should insert a line break, not evaluate the code.
