Access generates field in cmd

[CuckooEXE]

Is it possible to get this syntax working: access the generates items in the cmd? I'm big on DRY, so I'd like to not repeat this same information:

  myLib:
    desc: Create the library
    summary: |
      Create the library that myApp will use.
    deps: [create-libdir]
    sources: ["myLib/*.c"]
    generates: ["libmyLib.a"]
    cmd: gcc -static -o {{.GENERATES | first}} {{.SOURCES | join " "}}

[ShreeChaturvedi]

Drop the paths into vars, then reuse them in sources, generates, and cmd:

myLib:
  desc: Create the library
  deps: [create-libdir]
  vars:
    SRC: "myLib/*.c"
    OUT: libmyLib.a
  sources:
    - "{{.SRC}}"
  generates:
    - "{{.OUT}}"
  cmd: gcc -static -o {{.OUT}} {{.SRC}}

.GENERATES isn't on the special vars list. I'd leave myLib/*.c as a glob so the shell expands it. Task still fingerprints it.
