I hope I'm not running the risk of inducing Boost Unit burnout by making this request shortly after the review of Andy Little's proposal to add dimensional analysis and units to Boost...I'm hoping that the interest level will stay high enough to pull through one more review. Since the input from the recent informal review seems to have petered out, and I believe I've addressed the majority of the issues raised, this seems like an appropriate time to request a formal review of mcs::units. An issue that does concern me is feature creep - in the past, there seems to have been an ever-growing cycle of increasingly complex feature requests/needs/ desires. To try to focus the review, here is a summary of the intended scope of the library: mcs::units is a library providing zero-runtime overhead dimensional analysis for unit and quantity calculations. It provides support for 1) unit systems comprised of arbitrary sets of base units 2) arbitrary user-defined value types 3) support for heterogenous operator algebras (i.e. Z op(X,Y)) 4) support for basic outputting of quantities 5) optional support for implicit unit conversions It does not support 1) runtime units or quantities 2) input or parsing of quantities The most recent version (mcs_units_v0.5.7.zip) is in the Boost Vault (http://www.boost-consulting.org/vault/), in the Units directory. As always, comments/suggestions/requests are welcome.
