1) In a Python string it is available the \U{name} escape, where name is a character name in the Unicode database.
As an example: foo = u"abc\N{VULGAR FRACTION ONE HALF}" Hmm, looks nice, and sensible. But as soon as you've got \N{....} syntax I want: "foo\E{show i}bar"
How this should/can work? There is Text.Printf for this.
I vaguely recall seeing some TH go by that did this (albeit with $() TH foo).
Sometime they are necessary, to avoid circular import problems (but this not a problem with Haskell).

In practice GHC needs help with circular imports, and some cycles might be impossible to resolve. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
