Opening BAMs doesn't appear to return bool

[nellore]

var bam: Bam
assert open(bam, "myBam.bam", index = true)

gives

Error: type mismatch: got (void)
but expected one of: 
template assert(cond: bool; msg = "")

Am I missing something obvious? Thanks!

you can just use:

var bam: Bam
open(bam, "myBam.bam", index = true)

I have updated the remaining location in the docs that had the assert.

thanks for opening the issue and let me know any other problems.
