I'm following Yesod tutorial that gives this as the first example for
"type-safe URLs":
| getHomeR = defaultLayout [whamlet|<a href=@{Page1R}>Go to page 1!|]
Worked fine, the "a href" generated looks perfect.
Then I tried this:
| getHomeR = defaultLayout [whamlet|Hello!<a href=@{Page1R}>Go to page 1!|]
And got a "a href" referecing a URL without quotes and with no end tag
for "a", something like this:
| <html><head><title></title></head><body>Hello<a href=/page1>Go to
page 1!</body></html>
I tried in many different ways, and the only way to get it working
properly was to set the "a" tag in a line by itself:
| getHomeR = defaultLayout [whamlet|Hello!
| <a href=@{Page1R}>Go to page 1!
| |]
Is this a failure of Yesod quasiquotation or am I missing something?
I know Yesod clearly states that the best approach is to use external
files instead of quasiquotes, but as I'm making my first steps into
Yesod, I would like to use the practical embedded quasiquotes.

Hamlet is whitespace sensitive like haskell and python. If you put a tag after text, it is treated as text.
Write the <a... on the next line and it will work.

Another option is to manually put the closing </a> when the tag is in

the middle of the line. This is especially useful for tags such as
<em> or <strong>, e.g.
This is <strong>very</strong> important!
vs.
This is #
<strong>very
\ important!
