default params with type break the compiler

[georgejecook]

function CreateTestStatistic(name as string, result = "Success" as string, time = 0 as integer, errorCode = 0 as integer, errorMessage = "" as string) as object

this transpiles with my compiler, to valid brs, as follows:

function RBS_STATS_CreateTestStatistic(name as string, result = "Success" as string, time = 0 as integer, errorCode = 0 as integer, errorMessage = "" as string) as object

Howeverm the bs compiler produces the following error:

frameworkTests/source/tests/rooibosDist.brs:2043:75 - error BS1039: Expected newline or ':' after function signature

 2043  function RBS_STATS_CreateTestStatistic(name as string, result as string = "Success", time as integer = 0, errorCode as integer = 0, errorMessage as string = "") as object
