Interesting idea, XPM embeds images in C as C https://en.wikipedia.org/wiki/X_PixMap#XPM

[timotheecour]

how you pass that thru the review tho...

not sure if that comment applies to XPM or to embedBinary; for embedBinary the API should be clean:

something like this (similar to what i proposed in https://forum.nim-lang.org/t/8117#52130 but trying to turn it into an actual API):

# in std/backendutils:
type Blob* = object
  first*: ptr char
  n*: int

proc embedBinary*(a: static string): Blob = ...
proc toString*(a: Blob): string = ...

# in main.nim:
let blob = embedBinary("abc\0\tdef")
doAssert blob.toString == "abc\0\tdef"
