Deno "Error: illegal value for flag --max-old-space-size=4096 --expose-gc of type size_t"

 I'm using an old version of Deno (version 1.38.4) and when trying to use the --v8-flags= parameter on the command line, with more than one flag, I get this error:

Error: illegal value for flag --max-old-space-size=4096 --expose-gc of type size_t


The solution is trivial: Just use comma:

example:

--v8-flags="--flag-1=xpto,--flag-2"
