Interactively run Lasso code

The example below is taken from the lasso9 binary that allows you to interactively run lasso commands. The code displays a prompt to standard out and waits for input. It reads the input from standard in and tries to process it as Lasso code.


while(true) => {        
    stdout('>: ')
    local(r = file_stdin->readSomeBytes(1024, 1000))
    while(not #r or #r->size == 0) => {
        #r = file_stdin->readSomeBytes(1024, 1000)
    protect => {
        handle_failure => {
            stdoutnl(''+error_code+' '+error_msg)
        local(cb = sourcefile(string(#r), 'interactive', true, false))
