The YAML format does not allow for math or other convenience syntax. cobald could provide a YAML tag plugin for basic evaluation and unit replacement.

Before:

maxBytes: 10485760

After:

maxBytes: !eval 10 MiB

maxBytes: !eval 10 * 1024 * 1024

Possible to use ast.literal_eval for the evaluation part.

It could be worth using pyparsing to offer lambda support.
